Question

Which of the following is the correct classification of AMNP if m/M = 37° and m/P = 106° ?

A Right
B Isosceles
C Acute
D Scalene

Answer 1

B Isosceles

Explanation:

You want to know the classification of ∆MNP when ∠M = 37° and ∠P = 106°.

Third angle

The third angle of the triangle can be found using the fact that the sum of angles is 180°.

∠N = 180° -37° -106° = 37°

This tells us angles M and N have the same measure (37°), so ...

the triangle is isosceles.
