Question

△MNP≅△QST.

What is m∠S?



Enter your answer in the box.

Answer 1

78°

Explanation:

∠M=∠Q

∠N=∠S

∠P=∠T

Answer 2

• m∠S =78°

---------------------

Given

• Two congruent triangles △MNP≅△QST

We know that corresponding angles of congruent triangles are congruent (vertices in same order as name of triangle):

• ∠M ≅ ∠Q, ∠N ≅ ∠S, ∠P ≅ ∠T

Angle S corresponds to angle N, hence their values are equal:

• m∠S = m∠N = 78°
