Properties of rectangles, rhombuses and squares

Front

What is a rectangle?

Back

A rectangle is a quadrilateral with four right angles.

Front

What are the properties of a rectangle?

Back

1. Opposite sides are equal in length. 2. All angles are 90 degrees. 3. Diagonals bisect each other and are equal in length.

Front

What is a rhombus?

Back

A rhombus is a quadrilateral with all four sides of equal length.

Front

What are the properties of a rhombus?

Back

1. Opposite angles are equal. 2. Adjacent angles are supplementary. 3. Diagonals bisect each other at right angles.

Front

What is a square?

Back

A square is a quadrilateral with all sides equal and all angles equal to 90 degrees.

Front

What are the properties of a square?

Back

1. All sides are equal. 2. All angles are 90 degrees. 3. Diagonals are equal and bisect each other at right angles.

Front

How do rectangles, rhombuses, and squares relate to parallelograms?

Back

All rectangles, rhombuses, and squares are types of parallelograms, which means they have opposite sides that 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

If m∠BCE = 4x - 23 and m∠DCE = 5 + 5x, how do you find m∠BCE?

Back

Set the angles equal to each other and solve for x, then substitute back to find m∠BCE.

Front

What is the relationship between the angles in a rhombus?

Back

The opposite angles in a rhombus are equal, and the adjacent angles are supplementary.
