What is a parallelogram?

Back

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

Front

What are the properties of the opposite sides of a parallelogram?

Back

The opposite sides of a parallelogram are equal in length and parallel.

Front

What can be said about the opposite angles of a parallelogram?

Back

The opposite angles of a parallelogram 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 degrees.

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 each 110 degrees.

Front

What is the relationship between adjacent angles in a parallelogram?

Back

Adjacent angles in a parallelogram are supplementary, meaning they add up to 180 degrees.

Front

How do you find the area of a parallelogram?

Back

The area of a parallelogram can be found using the formula: Area = base × height.

Front

What is the formula for the perimeter of a parallelogram?

Back

The perimeter of a parallelogram is given by the formula: Perimeter = 2(a + b), where 'a' and 'b' are the lengths of the two pairs of opposite sides.

Front

If the lengths of the sides of a parallelogram are 5 cm and 10 cm, what is its perimeter?

Back

The perimeter is 2(5 cm + 10 cm) = 30 cm.

What is a special type of parallelogram where all sides are equal?

Back

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