Question

One angle of an isosceles triangle measures 80°. What measures are possible for the other two angles?

Answer 1

80 degrees and 20 degrees.

Explanation:

Isosceles means two angles are the same. If one angle is 80 degrees that means another angle is 80 degrees. The sum of all angles is 180 degrees. 80 degrees + 80 degrees = 160 degrees. After you do that you subtract 160 from 180 to get 20 degrees.
