SOLUTION: The base angles of an isosceles triangle are congruent. If the measure of each of the base angles is twice the measure of the third angle, find the measure of all three angles.

Let the angle at the top equal x
Then the other angles are 2x and 2x
The sum of the angles of a triangle is always 180 degrees
x + 2x + 2x = 180
5x = 180
x = 36
2x = 72
2x = 72
check
36 + 72 + 72 = 180
180 = 180
OK
