Question

question 3 of 10
assume △abc ≅ △def. if m∠a = 70°, m∠b = 47°, and m∠c = 63°, what is the measure of ∠f?
a. 63°
b. 47°
c. 70°
d. cannot be determined

Explanation:

Step1: Use the property of congruent triangles

Since \(\triangle ABC\cong\triangle DEF\), corresponding angles are equal. That is \(\angle A=\angle D\), \(\angle B = \angle E\), \(\angle C=\angle F\)

Answer:

A. \(63^{\circ}\)
