Answer 2

The figures below are special types of quadrilaterals. Trapezium A trapezium is a quadrilateral with exactly 1 pair of parallel sides. Parallelogram A Parallelogram is a quadrilateral with 2 pairs of parallel sides. Rhombus A rhombus is a parallelogram with 4 sides of equal length.
To prove that the opposite angles of a parallelogram are equal.
Construction: Draw a parallelogram ABCD. ...
Proof: In triangle ABD and BCD.
AB = CD [opposite sides of the parallelogram]
BC = DA [opposite sides of the parallelogram]
BD is common.
So triangles ABD and BCD are congruent.
Hence
