How to Determine Whether Three Points are the Vertices of a Right Triangle

[@viltelis6621]

With all of this quarantine going on, these types of videos really help

[@Greenemath]

I'm glad you found them helpful.

[@Ram_Rod45]

Thank you for showing multiple examples. I failed to realize that A squared + B squared = C squared. I couldn't figure out how the points even though they weren't the same created a vertices. thanks once again

[@Greenemath]

You're welcome!

[@conquerings583]

Honestly, you explain this stuff better than my teacher. I really appreciate, it you're really helpful.

[@Greenemath]

Glad to hear that!

[@33goldengirl]

Great explanation! Thank you so much!

[@Greenemath]

You're very welcome!

Three vertices of triangle A(6 -1 2) B( -2 3 -4) C(-3 1 5) Find distsnce btw AC and BC?? Plz solvr it

[@Greenemath]

I'm happy to help with questions about the video. Your homework is there for you to learn and master concepts.

[@coolstar7819]

you haven't written the question clearly

[@rayyanhashmi0]

take distance formula of ac then u find the answer for ac do the same thing for bc the distance formula u should already know of

[@Itouchnograss]

bro you just saved me for my geometry final

[@Greenemath]

The easier way is to use the matrix method. I would definitely not use this approach if you are pressed for time on an exam. Good luck!

[@Itouchnograss]

@@Greenemath ill be real, i was not expecting a response 4 years after the vid came out lol. ty

[@Greenemath]

@Itouchnograss You are welcome, I answer all my comments.

[@27locker]

Thank you so much for this video, this really helped me on my homework!

[@Greenemath]

Glad it helped! The method using determinants is a bit faster if you are familiar with matrices.

Day-12 Completed

[@Greenemath]

Did you skip to #73? You might want to do the section on absolute value equations and rational equations/inequalities.

[@harsh_sah]

@@Greenemath I only skip #65 to #72 which is radical and absolute value equation

[@Greenemath]

@harsh_sah Those are not the same as what you saw in the Algebra 2 course. #65 , #66, #71, and #72 are important. The #71 and #72 will teach you how to solve the harder case absolute value equations and inequalities. I think if you skip them it's okay but there are some things in there that are kind of important. Also after #99 there is an additional lesson on combination of graphing transformations that I don't have a link for yet. Let me know if you get there and there isn't a link yet and I'll give one to you.

This video reallyhelp me than god

[@Greenemath]

I'm glad it was helpful.

[@jaimeleerupisanavena2308]

how fo we determine which angle is 90°???

[@Greenemath]

It has a right angle symbol.
