Front

What is a parallelogram?

Back

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

Front

What is the property of opposite sides in a parallelogram?

Back

In a parallelogram, opposite sides 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 two angles of a parallelogram are 70 degrees, what are the other two angles?

Back

The other two angles are 110 degrees each, since opposite angles are equal and adjacent angles are supplementary.

Front

Solve for x: 2x + 5 = 15

Back

x = 5.

Front

What is the formula for the area of a parallelogram?

Back

The area of a parallelogram is given by the formula: Area = base × height.

Front

If the base of a parallelogram is 10 cm and the height is 5 cm, what is the area?

Back

Area = 10 cm × 5 cm = 50 cm².

Front

What is the relationship between the diagonals of a parallelogram?

Back

The diagonals of a parallelogram bisect each other.

Front

If one angle of a parallelogram is 60 degrees, what are the measures of the other angles?

Back

The other angles are 120 degrees, 60 degrees, and 120 degrees.

Front

Solve for x: 3x - 7 = 2x + 5

Back

x = 12.
