Question

at an archaeological site, the remains of two ancient step pyramids are congruent. if abcd ≅ efgh, find m∠efg. (diagrams are not to scale.)
m∠efg=
(do not include the degree symbol in your answer.)

Explanation:

Step1: Use the property of congruent polygons

Since \(ABCD\cong EFGH\), corresponding angles are equal. That is, \(\angle ABC=\angle EFG\).

Step2: Identify the measure of \(\angle ABC\)

From the first diagram, we can see that \(\angle ABC = 125\).

Answer:

125
