Question

An isosceles triangle has an angle that measures 90°. What measures are possible for the other two angles? Choose all that apply.

90 45 75 20

Answer 1

Isosceles triangle has two sides of equal length. The triangle with the tree sides has to sum up to 180 degrees
Therefore 45 degrees is your answer

Answer 2

Explanation:

All three angels of a triangle have to sum to 180 degrees ....so there is only 90 degrees left for the other two equal-sized angles (isosceles).....they must be 45° each
