ΔTIC is an isosceles triangle with vertex angle I. Find the measures of the base angles of ΔTIC if m∠I = 100º.

A)80°

B)50°

C)60°

D)40°

It would be D: 40 degrees. This is because in an isosceles triangle, the base angles are the same and since the measure of a triangle equals 180 degrees, the base angles would be 40 degrees because 100+40+40 = 180.
