Question

One angle of an isosceles triangle measures 72°. Which other angles could be in that isosceles triangle? Choose all that apply.

54°
59°
36°
72°

Answer 1

72 and 36

Explanation:

Since it is an isosceles triangle we know that one of the angles will be 72 degrees as well. I added both of the 72s and got 144. A triangle has 180 degrees. Subtract 144 from 180 and you get 36.
