Question

Identify the triangle, ABC, which has a 72∘ angle and a 36∘ angle.

Answer 1

isosceles acute

Explanation:

sum of angles in a triangle = 180

to find third angle, subtract 72 & 36 from 180 and you get 72

72, 36, and 72 are all less than 90 so it will be an acute triangle

It will also be isosceles bc there are 2 angles of the same measure
