Unit 6 Day 1 - Parallelogram Properties

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 the diagonals of a parallelogram?

Back

The diagonals of a parallelogram bisect each other.

Front

If two angles of a parallelogram are 70 degrees, what are the measures of the other two angles?

Back

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

Front

What is the formula for the area of a parallelogram?

Back

Area = base × height.

Front

In a parallelogram, if one angle measures 60 degrees, what are the measures of the other angles?

Back

The opposite angle is also 60 degrees, and the other two angles are 120 degrees each.

Front

How do you find the length of a side of a parallelogram if you know the area and height?

Back

Length of side = Area / height.

Front

What is the relationship between the opposite sides of a parallelogram?

Back

The opposite sides of a parallelogram are equal in length.

Front

If the lengths of the sides of a parallelogram are 5 cm and 12 cm, what is the perimeter?

Back

Perimeter = 2 × (5 cm + 12 cm) = 34 cm.

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

Back

It is a rectangle.
