An isosceles triangle MNP has one angle, N with a measure of 20degrees. The angles M and P are congruent. Which is the measure of angle P?

A.10degrees

B.70 degrees

C.80 degrees

D.160 degrees

C. 80 degrees

Step-by-step explanation:

Sum of interior angles of triangle = 180

since M and P are congruent, they have same degree

therefore:

2x + 20 = 180

x = 80

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
