Evaluating a 30-60-90 triangle
The short leg is always between the 60 and 90. This leg is always the one we use to measure.
The long leg is always
times longer than the short legThe hypotenuse (diagonal) is always twice the short leg
6
Multiple Choice
Given that 5 is the short leg, what is the length of the long leg, b?
7
b =
To find the long leg: take the length of the short leg and multiply it by
8
Multiple Choice
Given that 5 is the short leg, what is the length of the hypotenuse, c?
9
c = 10
To find the hypotenuse, take the length of the short side and double it.

Find n and m
Since 12 is the hypotenuse, we know that 12 = 2n (because the hypotenuse is always 2 times the short leg
Know that 12 = 2n
divide by 2
n = 6
