4.1 Flashcardizz. Properties of Parallelograms

Front

What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

Front

What are the properties of opposite angles in a parallelogram?

Back

In a parallelogram, opposite angles are equal.

Front

What is the sum of the interior angles of a parallelogram?

Back

The sum of the interior angles of a parallelogram is 360°.

Front

What is the relationship between consecutive angles in a parallelogram?

Back

Consecutive angles in a parallelogram are supplementary, meaning they add up to 180°.

Front

What happens to the diagonals of a parallelogram?

Back

The diagonals of a parallelogram bisect each other, meaning they cut each other in half.

Front

If one angle of a parallelogram is 95°, what are the measures of the other angles?

Back

The opposite angle is also 95°, and the consecutive angles are each 85°.

Front

How do you find the length of a diagonal in a parallelogram?

Back

Use the properties of triangles formed by the diagonals and the sides of the parallelogram, often applying the Pythagorean theorem.

Front

What is the formula for the area of a parallelogram?

Back

The area of a parallelogram is calculated as Area = base × height.

Front

What is the relationship between the sides of a parallelogram?

Back

In a parallelogram, opposite sides are equal in length.

Front

What is the significance of the diagonals in a parallelogram?

Back

The diagonals can be used to determine the properties of the parallelogram, such as its area and the lengths of its sides.
