Question

Given △ABC ≅ △DEF .

What is the measure of ∠E ?



Enter your answer in the box.


m∠E = °

A triangle with vertices labeled A B and C. Angle A has a right angle symbol. Angle B measures 60 degrees. Angle C measures 30 degrees. A second triangle with vertices labeled D E and F.

Answer 1

Answer: m∠E = 60°

Explanation:

Answer 2

Answer: m∠E = 60°

Explanation:

Here, ABC and DEF are two triangles in which,

m∠A = 90°, m∠B = 60° and m∠C = 30°

Also, Δ ABC ≅ Δ DEF

Thus, By CPCTC ( congruent part of congruent triangles are congruent )

m∠A = m∠D = 90°

m∠B = m∠E = 60°

m∠C = m∠F = 30°

Hence, the measurement of angle E is 60 degree.
