What are the properties of a parallelogram?

Back

A parallelogram has opposite sides that are equal in length, opposite angles that are equal, and the diagonals bisect each other.

Front

How do you find the area of a rectangle?

Back

The area of a rectangle is found by multiplying its length by its width (Area = length × width).

Front

What is the sum of the interior angles of a quadrilateral?

Front

How do you determine if a quadrilateral is a rhombus?

Back

A quadrilateral is a rhombus if all four sides are of equal length or if the diagonals bisect each other at right angles.

Front

What is the formula for the area of a rhombus?

Back

The area of a rhombus can be calculated using the formula: Area = (d1 × d2) / 2, where d1 and d2 are the lengths of the diagonals.
