What is a quadrilateral?

Back

A quadrilateral is a polygon with four edges (sides) and four vertices (corners). Examples include squares, rectangles, rhombuses, and trapezoids.

Front

What are the properties of a rhombus?

Back

A rhombus has all sides of equal length, opposite angles are equal, and the diagonals bisect each other at right angles.

Front

If two angles of a parallelogram are 70 degrees, what are the measures of the other two angles?

Back

The other two angles are 110 degrees each, as opposite angles in a parallelogram are equal and adjacent angles are supplementary.

Front

What is the relationship between the diagonals of a rectangle?

Back

The diagonals of a rectangle are equal in length and bisect each other.

Front

In a rhombus, what is the relationship between the angles?

Back

Opposite angles are equal, and adjacent angles are supplementary (add up to 180 degrees).

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.
