PROPERTY OF TRAPEZIUM

__TRAPEZIUM -__

**In quadrilateral when one pair of sides is parallel, is considered as a trapezium. In the figure, ABCD is a trapezium in which AB || DC but AD is not parallel to BC. AD & BC are called oblique sides.**

**AB || DC, **

**So, ∠A + ∠D =
180⁰**

**And, ∠B + ∠C
= 180⁰**
