8-2 Parallelograms (Flashcardizz)

Front

What is a parallelogram?

Back

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

Front

What are the properties of the angles in a parallelogram?

Back

In a parallelogram, consecutive angles are supplementary, meaning they add up to 180 degrees.

Front

What is the relationship between the diagonals of a parallelogram?

Back

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

Front

If ABCD is a parallelogram, what can be said about the lengths of sides AB and CD?

Back

In a parallelogram, opposite sides are equal in length, so AB = CD.

Front

If the measure of angle A in parallelogram ABCD is 70 degrees, what is the measure of angle C?

Back

Angle C is also 70 degrees because opposite angles in a parallelogram are equal.

Front

If the measure of angle A in parallelogram ABCD is 70 degrees, what is the measure of angle B?

Back

Angle B is 110 degrees because consecutive angles in a parallelogram are supplementary (70 + 110 = 180).

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.

Front

If the base of a parallelogram is 5 cm and the height is 4 cm, what is the area?

Back

The area is 20 cm² (Area = 5 cm × 4 cm).

Front

In a parallelogram, what can be said about the lengths of sides AD and BC?

Back

In a parallelogram, opposite sides are equal in length, so AD = BC.

Front

If the diagonals of a parallelogram are equal, what type of parallelogram is it?

Back

If the diagonals of a parallelogram are equal, it is a rectangle.
