Properties of Rhombus:
1) A flat shape with 4 equal straight sides. It looks like a kite or a diamond.

3) opposite sides are parallel and opposite angles are equal
4) the diagonals bisect each other at a right angle.
5) the altitude is the distance at right angles to two sides
∠CED is a right angle : GIVEN
AB congruent to CD : all sides have equal length
DB bisects AC at E : diagonals bisect each other at a right angle.
