Special Right Triangles - 30 60 90 - Geometry & Trigonometry | SAT Math
This video tutorial provides a basic introduction into 30-60-90 triangles. It explains how to find the value of the missing side of other triangles using the 30-60-90 reference triangle. This information is useful for high school and college students studying geometry and trigonometry and for students studying the SAT math and ACT math sections. This tutorial contains plenty of examples and practice problems.

MR. Organic Chemistry Tutor, thank for another fine explanation of the 30-60-90 Special Right Triangles
If you guys don't get it, here is a simpler way: Let the side across the 30 degree angle have a side length of x. Let the hypotenuse be 2x, and let the side across the 60 degree angle be x times sqrt(3). Using algebra, you can find different side lengths by having one. For example, if the hypotenuse of a 30-60-90 triangle is 54 units long, the side across the 30 degree angle is 27 units, and the remaining side length is 27 sqrt(3).

My initial confusion before coming to this with no prior knowledge is the x, which I thought there was a variable, but, I come to find out that's it multiplication. THX

The line that's in the front front of the angle is going to be the 30-60-90, also remember that the line that is in front of the mini square in the triangle is going to be the line 90

Around 3:26 you mention going 30 to 60 and having to multiply by square root three but the triangle calls for a 60 to 30 so wouldn’t you actually divide by square root three and get 12 instead of 36?
@AdinRossTakes

bro what im more confused about what an angle is
Why is ut the square root of 3 what rule makes that possible and with the 45 45 9i triangle it’s square root of 2 instead of 3
I’m confused, How we know when that we have to find the hypotenuse side or the legs of the triangle side first?
@cliph1022

Look at the given first, if the hypotenuse side is already given then find the other two sides, if one side is given, then find for the hypotenuse then the other side, just look at the given that is given to you xd

3:34 why would you multiply? you dont explain why you do some steps
Hi JM, i know that this is pretty old since posting, but hoping you can explain. around 6:03 you have one side 24 units, that's longer than the hypothenus. Please if possible, respond. PS. like your videos.

Heyo As a Mad Scientistbi shall give you my Best answer which is simply that I Belive he messed up the Sides as 24 Should be The Hypotenuse and 16√3 Should be the Corresponding angle to the 60°

When going from 90 to 30, you’re looking for the shorter side. So u have to divide.
