Parallelogram Theorem Proof 4:Diagonals of a quadrilateral bisect each other at right angles, then it is a rhombus
In this video we will learn how a parallelogran is a rectangle, provided diagonals of a parallelgram are equal.
In this video, we learn how to apply Congruency Rule to solve Problems on Qudrilaterals. Use parallel lines concept and triangle congruence theorems to prove/solve problems on properties of parallelograms.
