30 - 60 - 90 Triangles: GRE / GMAT Geometry

Everyone's favourite! 30:60:90 triangles are understood properly by very few students, I can almost guarantee you will learn something from this video if you are studying for the GRE or GMAT (or other exam this topic comes up in) and watch to the end. Triangle ratios come up occasionally in these tests but you can give yourself a big edge by understanding them!

The GRE and GMAT are two of most used graduate exams for those seeking to study a Masters Degree or Masters in Business Administration (MBA) degree. The Graduate Record Exam and Graduate Management Admissions Test have been taken for over 50 years and are taken by approximately 600,000 and 300,000 people worldwide annually, respectively. These exams are typically taken between the ages of 18-40, by those who have completed, or are about to complete, their Bachelors Degree.
Enquiries: [e-mail] If you’re now ready to get into your dream MBA program, my former student, Angel, is offering virtual private Admissions coaching. She was admitted into Harvard Business School, The Wharton School of Business, and Columbia Business School (accepted into every school she interviewed for) after graduating from UCLA with a degree in Communication. She also got 3 perfect scores on the GRE’s Analytical Writing Assessment (99th percentile).

the first thing i do in the morning and the last thing in the night is watching your videos.. i have watched multiple other videos but nothing like the way you explain.. best content for gre on KZbin!! Thank you

[@TheTestedTutor]

That's lovely to hear Roopa :)

[@anahitapatkar4515]

Hi Philip I'm really not one to comment on social media but you really deserve a shoutout! My GMAT is in under 10 days and I haven't been able to dedicate the time to study as much as I hoped with a very hectic job! I was panicking about how far behind I am but your videos give me a reassuring sense of calmness and confidence. Thanks much!

[@daminivadrevu3027]

You're amazing! Would love more videos on parallelograms, trapezoids and 3D figures, - geometry! ❤️ Love from India

[@iyanuoluwaaliu5539]

You caught me! But I won’t hang my head in shame 😂😂😂 Thanks for these tricks, Phillip.

[@indian_scouser_ynwa]

Great tip : Just because it looks like a right triangle, doesn't mean it is!! Fallen for it many times. Gotta peruse the question and be vigilant. Your videos, as always, are edifying and repleted with cornucopia of virtuosity.

[@TheTestedTutor]

Haha thanks ab!

You are so amazing. Your teaching method really helps to crack problems in few steps.

[@mrs.m2571]

Wow! Thank you so much. I was so confused before this.

[@aaaaammmmmyyyyyy]

Thank you so so so much. When i watch other videos i sometimes have to watch them a couple times to understand the concepts, but you explain so simply and eloquently that I understand mostly everything on the first go! Wow, also I'm so mad they never taught this box trick while i was in school haha !

[@lubainabhori6530]

I have learnt so much quicker through you videos. Please make a video on finding missing lengths in similar triangles (3 triangles also). Since these type of questions seems pretty time consuming. Thank you!!!

[@TheTestedTutor]

Great idea! Will do

[@sumaiyaakterbanna8071]

Sir, your videos are so much helpful for my GRE preparation. I have been loved with the ways you explain the concepts and examples. You are an awesome tutor I have ever seen. Can you please make video on 45-45-90 degree triangle? Hope you will upload more videos on GRE. Love from Bangladesh.

[@cardiyansane1414]

@ 13:39 example , maybe this is overthinking but I thought to use pythagorean theorem to find find line AC which will correspond with angel ABC then form an algebraic equation based on the values of the side we are given .i.e 90 degrees corresponds with 16 therefore ac can be found by forming an equation that "matches " the two . Totally different angles but they add up to 180 ?

[@michaelanaelechi54]

Thank you 🤝🤝🤝

[@AnsImran]

Thanks

[@akashmishra3369]

Hey Phillip, I came across a similar question as the last one in one of the practice tests and instead of giving us an angle, it was given that CB is equal to the radius of the circle, I got that question wrong as I didnt know what to do. Thanks for your trick.

[@NerdsPwnN00bs]

I really wish you’d make a list of short hand math. As an engineer grad, I know these maths skills, but they’ll just take me a while. It’ll prolly be too late for me, but for others.

[@juanamariasolanomesa8671]

[@hassaanraza1090]

Nope! Much more to tell. Try to finish the Manhattan 5lb guide...

[@loopm1599]

Hi.... how do we determine which side is the height in the last example (17: 50)?

[@TheTestedTutor]

Any perpendicular side actually

[@murtalaa]

I feel like i was in high school 19 yrs ago, only with a better version of my high school math teacher.

[@colleenmadden11]

For the "bring it all together question", I still do not understand how you know which side is the hypotenuse. If when looking at figures on the GRE you should know things may not be drawn to scale, how do you know whether the diameter with center O is either the hypotenuse or larger side?

[@colleenmadden11]

is the angle opposite to the diameter with the center on it always the 90 degree angle?

[@TheTestedTutor]

Diameter must be longest side

[@lonen3rd]

@@colleenmadden11 probably too late but could help someone. The angle inscribed in a semi-circle is always a right angle. So in this case, angle ACB is by default 90°.

[@bradleygoronson9698]

Love it! Very well done.

[@TheTestedTutor]

Thank you! Cheers!

[@96_vaidehisudele2]

Hey Phillip! In the question @6:31 if we write x√3=12 and then x√3=2√3 it gives x=2 which changes every side of the triangle. is there something wrong with this approach? please help..
