GCSE transformations: enlargement by positive and negative scale factor

GCSE mathematic revision help, golden rules when enlarging by a positive or negative scale factor. Two examples of how to enlarge a shape by a positive and negative scale factor for GCSE revision.
The first example is how to enlarge by a scale factor of 2
The second example is how to enlarge by a negative scale factor of -2
A scale factor of 2 and -2 is chosen. This is one of the key GCSE transformations and will help secure a grade 4 and above in your GCSE examination View my channel: / jayates79

A compilation of my videos and revision resources ordered by grade at GCSE are being added to mathslearn.co.u...

its funny how people on youtube can teach better than the teachers at school

[@estherobeng6603]

Lol that's so true

[@Beth_2036]

AliciaTestarossa0034 for real

[@thewholockgaming3616]

agree

[@alialshaikh8816]

Yea😂🤣

[@AmyLangdon03]

AliciaTestarossa0034 he's a teacher at my school

[@sea5205]

Compare this to the Mandarin my maths teacher was speaking in class

[@MathslearnCoUkvideos]

Yes, you can enlarge by -1. From the centre of enlargement,: coordinate A would go left one down 1 coordinate B would go left one down 3 coordinate C would go left 5 down 3

[@wis4082]

this is the best explanation ever, you are 100000 times better than my mean teacher, thank you so much!!!!!!!!!!!

[@kirstynlyons4195]

Yes! Thank you I get it now! Your a life saver I couldn't understand what my teacher meant but I get it now yay! Thank you again!

[@rexyrex2587]

Mr Jayates, you are a the BEST maths teacher i have ever seen. I am student who does GCSE examinations. I'm doing Biology,Chemistry,Physics and Maths,i appreciate your work that you are doing to students like us because at school we are not thought much well like the way you teach...... so i really thank you....may God bless you!

[@_NOBODY_8888]

[@palestasza]

[@tofire2261]

Oh my god i've got it! Thank you so much, it was easyer than i tought. My teacher made it look so difficult and i understood nothing. Thank you. Tomorrow i have a really important test and i am studying everything we've done, and because i didn't understand most of it it's gonna be a long day ^^;; But thank you. Now i get more about these enlargements.

[@markcalderwood3948]

very informative! VERY clear! Thank you!

[@fawadraza2404]

Thanks a lot, finally , I clearly understood enlargement, I wish I had seen your video few days before my exam, I left one question 😞

[@lilianbanda5970]

thanks, this was very helpful! end of year test tomorrow

[@itsadolphinlmao_1593]

Lmao got mine tmoz

[@MathslearnCoUkvideos]

The same method is used - just mark the coordinate (2,2) for example as the origin and go through the same process looking how to get from (2,2) to each of the corners of the shapes and then applying the scale factor as appropriate.

[@jehanzebkhan9339]

I’m confused for the minus two because aren’t you going left 3 down 3

[@hamzaali7205]

Where you getting 6 from

[@mahir1455]

[@MCWolfyGamer]

Great video! Helped a lot.👍

[@vandomog1013]

It's a very good video for someone, who is new to this topic. Thanks for making the topic scale factor, simple to understand.

[@Om287]

thank you you are the best teacher

[@wanh33da69]

thanks, helped me so much

[@infires2013]

thank you, got an extra 10 mins on mY maths exam today- this really helped.

[@lukeandjim1701]

Luke: Isn't it amazing. Jim: What? Luke: The enlarged triangles are similar to the small triangle. Jim: Oh yes. And corresponding sides are parallel. Luke: And the two enlarged triangles are congruent. Jim: I wonder why these things are true? Luke: Those are mathematical questions, Jim. Jim: Sorry, Luke, I forgot we were just revising procedures.

[@hamood143]

Mrs1234ist: look I had the same question it's not confusing look here how it's done if the coordinates of A is (8,4) this means across eight up four so what u do is if the scale factor is 1/2 u just take the half of each number so if u have (8,4) u take the half of each it will be like this (4,2) hope this helps you

[@mrjelyfishtv3665]

Nice video content! Sorry for chiming in, I would appreciate your initial thoughts. Have you considered - Lantslay Bigger Man Domination (google it)? Ive heard some great things about it and my friend eradicated the small d1ck nightmares with it.

[@Alexiagold6]

When doing enlargement i have heard that you need to add the lines as well? but this one doesn't have the lines and i think that in a test thats what you get the marks for too.. the lines ? So do the Lines HAVE to be there?

[@Natashahoneypot]

This video could be titled ASMR Maths. 3 hours of super relaxing perfect explanation.

[@justdina5522]

very clear and helpful, I understood it immediately thank you

[@adamfoster3217]

It's also funny that I just spent a whole hour try to understand the poorly written, complicated text book, yet he just explained everything in under 4 minutes

[@rudaina61]

can anyone please tell me how to enlarge with a specific centre? Like scale factor -4 with (0,1) ? :)

[@jasonhessing]

For the negative factor instead of going left (a for example) can you take down 1 left 1 instead of left 1 down 1?

[@duaaesam9460]

really good man ...I mean my teacher is a good one but idk this lesson....she didnt explain it good at all ...so thx

[@connorf561]

thanks helped me on HW wont get detention now

[@saryjohannes5322]

thanks,you should do more clips on this with different examples.

[@redlightchild9988]

i would subscribe man but after tomorrow i'll never need to know GCSE maths again. Cheers for the help though!

[@StLuciaAviation]

thanks you alot this helped me very much

[@kadeshaanderson3039]

Thanks, u made this so easy. My lecturer didnt teach me but now i understand to go do my exam in a short while.

[@lifeishard8912]

[@evethomas2289]

[@georgehawkins360]

This is such a helpful video thank I have a test Thursday about this and it’s very useful

[@ridaaa_25]

If only I watched this god dang video before my monthly assessments smh.

[@mel-kr2xu]

i got so nervous that i skipped the transformation question on maths paper 1 :( i did so bad

[@TheTravelList2024]

Well.....how about from different origins such as (2,2) or some other

[@olliebridges4703]

Thank you! Really helped for my maths exam tomorrow ;)

[@derekyong8878]

dont u feel like sherlock is teaching u math (the voice of the guy)?

[@fatimashirazi4842]

It's weird that I learnt more watching this video then an hour long lesson at school.

[@2crazy4sa]

wow thanks a lot... my textbook seriously failed to explain this thing in simple way

[@hellomrbeetle]

What if you have a factor of enlargement that is a fraction? like 1/3 or something?

[@StephenRhysCollins]

Just did this in an exam.. Everyone said that I had done it wrong. But I haven't :)

[@Devious90210]

THANKK YOU so much really helped :D

[@imaanjaffer4060]

finally got it after soooooooo long thanks awsome video saved me for maths tmrw

[@acupoftea0384]

[@patmentoring6391]

Dude you voice sounds like the guy from the witch

[@mujtabazaki282]

8years ago 2020 schools : Why not having a test this late

[@nuramoboy]

Thanks for the Video,but why has the triangle turned 180 degrees? x

[@leticiat1601]

Abdul's collection it's negative and the given space are counted which gives you that result

[@domdunster4707]

A bit boring but very helpful, thank you seer

[@elms4405]

thanks i have the IG math 0580 tommorow any tips anyone

[@vipezxlegend9401]

good work here, but can you next time do it on a isometric grid :]

[@amy_menzies]

I have to do one woth the scale factor of -1 1/2 could you help x

[@xNik]

-1 1/2 or -1.5 is basically the same thing, but instead of moving down by the opposite way you move to the original point you move 1+ half

[@Bilal-mh7gc]

Thanks. This was very much helpful.

[@miaxx4248]

Aha thanks so much I actually get how to do this now :))(

[@abayomiokunuga8778]

[@fandomqueen8250]

Got a test tmrw and this video helped me loads. Thx

[@abigailfallis3422]

so for a scale factor of 3 or 4 we go up by those numbers from the centre of origin yes?

[@xNik]

If scale factor is three then we take the point and move from C.O.E. 3x the point number

[@umaeratifkhan269]
