Parallelogram

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 a parallelogram?

Back

1. Opposite sides are equal in length. 2. Opposite angles are equal. 3. The diagonals bisect each other.

Front

How do you calculate the area of a parallelogram?

Back

Area = base × height.

Front

If the base of a parallelogram is 12 units and the height is 5 units, what is the area?

Back

Area = 12 units × 5 units = 60 square units.

Front

What is the height of a parallelogram?

Back

The height is the perpendicular distance from the base to the opposite side.

Front

If a parallelogram has an area of 32.94 square centimeters and a base of 12 centimeters, what is the height?

Back

Height = Area / Base = 32.94 cm² / 12 cm = 2.745 cm.

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 70 degrees, what are the measures of the other angles?

Back

The opposite angle is also 70 degrees, and the adjacent angles are 110 degrees each.

Front

What is the perimeter of a parallelogram with sides of 8 cm and 5 cm?

Back

Perimeter = 2 × (length + width) = 2 × (8 cm + 5 cm) = 26 cm.

Front

What is the area of a parallelogram with a base of 20 units and a height of 3 units?

Back

Area = 20 units × 3 units = 60 square units.
