Front

What is a parallelogram?

Back

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

Front

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

Back

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

Front

What are the properties of a rhombus?

Back

A rhombus is a type of parallelogram where all four sides are of equal length, opposite angles are equal, and the diagonals bisect each other at right angles.

Front

How do you find the measure of an unknown angle in a parallelogram?

Back

In a parallelogram, opposite angles are equal, and adjacent angles are supplementary (sum to 180 degrees).

Front

What is the relationship between the angles in a rhombus?

Back

In a rhombus, opposite angles are equal, and adjacent angles are supplementary.

Front

If one angle of a parallelogram is 62 degrees, what is the measure of the opposite angle?

Back

The opposite angle is also 62 degrees.

Front

If two angles of a parallelogram are 90 degrees, what type of parallelogram is it?

Back

It is a rectangle.

Front

What is the formula for the area of a parallelogram?

Back

Area = base × height.

Front

If the diagonals of a rhombus are 10 cm and 24 cm, what is the area?

Back

Area = (diagonal1 × diagonal2) / 2 = (10 × 24) / 2 = 120 cm².

Front

What is the difference between a rectangle and a rhombus?

Back

A rectangle has opposite sides equal and all angles are 90 degrees, while a rhombus has all sides equal and opposite angles equal.
