Question

Given polygon DEFGH ≅ polygon QRSTU . What is the measure of ∠R ? Enter your answer in the box. m∠R = ° An irregular pentagon with vertices labeled D E F G and H. Angle D measures 60 degrees. Angle E measures 143 degrees. Angle F has a right angle symbol. Angle G measures 102 degrees. Angle H measures 145 degrees. A second irregular pentagon with vertices labeled Q R S T and U.

Answer 1

143

Explanation:

Answer 2

Typically the letters in each figure correspond to the same letter in the second figure so D = Q, E = R, etc.

You are told E = 143, so since E = R , then R should also be 143 degrees.
