What are some properties of rhombus
Equal Sides: A rhombus is a special type of parallelogram in which all four sides are of equal length.
Diagonals: The diagonals of a rhombus bisect each other at right angles (90 degrees). That is, the point where the diagonals intersect divides each diagonal into two equal segments, and the angles formed at that intersection are right angles.
The sides and diagonals help us prove the congruence by SSS
