Flashcard - 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

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

Back

The measure of an angle in a parallelogram can be found using the property that opposite angles are equal and adjacent angles are supplementary (sum to 180 degrees).

Front

What is a rhombus?

Back

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

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

How do you calculate the sum of the interior angles of a polygon?

Back

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

Front

What is the sum of the exterior angles of any polygon?

Back

The sum of the exterior angles of any polygon is always 360 degrees, regardless of the number of sides.

Front

If RSTU is a square, what is the relationship between its sides?

Back

In a square, all four sides are equal in length.

Front

How do you find the length of a side in a square if given the area?

Back

To find the length of a side in a square, take the square root of the area.

Front

What is the formula for the area of a parallelogram?

Back

The area of a parallelogram is calculated using the formula: Area = base × height.
