Parallelograms

Front

What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

Front

What are the properties of a parallelogram?

Back

1. Opposite sides are equal in length. 2. Opposite angles are equal. 3. The diagonals bisect each other.

Front

How do you find the area of a parallelogram?

Back

Area = base × height.

Front

What is a rhombus?

Back

A rhombus is a type of parallelogram where all four sides are of equal length.

Front

What is the relationship between the angles in a parallelogram?

Back

The sum of the interior angles of a parallelogram is 360 degrees.

Front

If one angle of a parallelogram is 70 degrees, what are the other angles?

Back

The opposite angle is also 70 degrees, and the adjacent angles are 110 degrees each.

Front

What is the difference between a rectangle and a rhombus?

Back

A rectangle has four right angles, while a rhombus has all sides equal but angles can vary.

Front

What is the formula for the perimeter of a parallelogram?

Back

Perimeter = 2 × (base + height).

Front

What are the diagonals of a parallelogram?

Back

The diagonals of a parallelogram are the line segments that connect opposite vertices.

Front

How do the diagonals of a parallelogram behave?

Back

The diagonals bisect each other, meaning they cut each other in half.
