Question

Diane says that if she knows only the measure of one angle in an isosceles triangle, she can always determine the measures of the other two angles. James disagrees with her.

Who do you think is correct, Diane or James?

Answer 1

Diane

Explanation:

If Diane's measure is a base angle she subtracts the angle multiplied by 2 from 180 degrees, she ends up with the missing measure, otherwise she would subtract the angle and end up with the sum of the identical base angles
