Question

An isosceles triangle has an angle that measures 90°. Which other angles could be in that isosceles triangle? Choose all that apply.

Answer 1

Explanation:

If one angle = 90 degrees, then the other 2 added together must also = 90.

There is only 1 answer to this, since the triangle is isosceles..

x + x = 90 Combine

2x = 90 Divide by 2

x = 90/2

x = 45

So both acute angles = 45 degrees.
