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 find the area of a parallelogram?

Back

Area = base × height.

Front

What is the relationship between the angles in a parallelogram?

Back

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

Front

If one angle of a parallelogram is 70 degrees, what are the other angles?

Back

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

Front

What is the formula for the perimeter of a parallelogram?

Back

Perimeter = 2 × (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 significance of the diagonals in a parallelogram?

Back

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

Front

How do you solve for x in a parallelogram when given angles?

Back

Set up an equation using the properties of angles (e.g., supplementary or equal) and solve for x.

Front

If two sides of a parallelogram are equal, what type of parallelogram is it?

Back

It is a rhombus.
