Prepare a table with all the properties of parallelogram (square,rectangle,etc.).Also find relations among them if any.

A parallelogram is a flat shape with opposite sides parallel and equal.

The properties of a parallelogram are as follows:

i. Opposite sides of a parallelogram are parallel and equal.

ii. Opposite angles of a parallelogram are of equal measure.

iii. The adjacent angles in a parallelogram are supplementary.

iv. The diagonals of a parallelogram are not always equal. However, they bisect each other.

Square-

1) A plane figure with four equal straight sides and four right angles.

2) All interior angles 90°

3) The diagonals bisect each other at right angles.

Rectangle:

(**1)** opposite sides that are parallel,

**(2)** opposite angles that are congruent,

**(3)** opposite sides that are congruent,

**(4)** consecutive angles that are supplementary, and

**(5)** diagonals that bisect each other.

(**6)** All four angles of a rectangle are right angles.

**(7)** The diagonals of a rectangle are congruent.

* Rhombus-* A rhombus is a quadrilateral with four congruent sides.

Similar to the definition of a rectangle, we could have used the word "parallelogram" instead of "quadrilateral" in our definition of rhombus. Thus, rhombuses have all of the properties of parallelograms (stated above), along with a few others.

Let's look at these properties.

**(1)** Consecutive sides of a rhombus are congruent.

**(2)** The diagonals of a rhombus bisect pairs of opposite angles.

**(3)** The diagonals of a rhombus are perpendicular.
