Classifying Quadrilaterals

Front

What is a quadrilateral?

Back

A quadrilateral is a polygon with four sides, four vertices, and four angles.

Front

What are the properties of a parallelogram?

Back

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

Front

What defines a rhombus?

Back

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

Front

If one angle of a parallelogram is 50 degrees, what are the measures of the other angles?

Back

The opposite angle is also 50 degrees, and the adjacent angles are 130 degrees each.

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

How do you find the measure of an angle in a rhombus if one angle is known?

Back

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

Front

What is a trapezoid?

Back

A trapezoid is a quadrilateral with at least one pair of parallel sides.

Front

If a parallelogram has one angle measuring 74 degrees, what are the measures of the other angles?

Back

The opposite angle is also 74 degrees, and the adjacent angles are 106 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 does not require right angles.

Front

How do you classify a quadrilateral with one pair of parallel sides?

Back

It is classified as a trapezoid.
