Question

In quadrilateral ABCD, measure angle A+measure angle C=120 Find
measure angle B+ measure angle D

Priyanka Kedia · Accepted Answer

We know that, sum of angles of a quadrilateral are 3600
So, in quadrilateral ABCD,∠A+∠B+∠C+∠D=3600⇒∠A+∠C+∠B+∠D=3600⇒1200+∠B+∠D=3600⇒∠B+∠D=2400

In quadrilateral ABCD, measure angle A+measure angle C=120. Find measure angle B+ measure angle D
