6. Trapezoids and Kites
Sign In
If a quadrilateral is an isosceles trapezoid, then each pair of base angles is congruent.
110
We want to find the measure of ∠QPS in the given isosceles trapezoid. Let's start from drawing the graph.
We are given that m∠PQR = 110. Recall that in isosceles trapezoid the base angles are congruent. Therefore angles ∠PQR and ∠QPS are congruent, so their measures are equal. m∠QPS = m∠PQR ⇕ m∠QPS=110
