Polygons and Quadrilaterals

Front

What is a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments connected end to end.

Front

What is a quadrilateral?

Back

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

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 one interior angle of a regular polygon?

Back

To find the measure of one interior angle of a regular polygon, use the formula: (n-2) × 180° / n, where n is the number of sides.

Front

What is the measure of each exterior angle of a regular polygon?

Back

The measure of each exterior angle of a regular polygon is 360° / n, where n is the number of sides.

Front

What types of quadrilaterals have perpendicular diagonals?

Back

Quadrilaterals with perpendicular diagonals include rhombuses, squares, and kites.

Front

In a kite, what is true about the angles between the unequal sides?

Back

In a kite, the angles between the unequal sides are equal.

Front

What is a regular polygon?

Back

A regular polygon is a polygon with all sides and all angles equal.

Front

If one angle of a regular pentagon is 108°, how many sides does it have?

Back

A regular pentagon has 5 sides.

Front

What is the relationship between the sides and angles of a polygon?

Back

The number of sides of a polygon determines the sum of its interior angles, which can be calculated using the formula (n-2) × 180°.
