Properties of Parallelograms and Rectangles

Front

Do diagonals of a rectangle bisect each other?

Back

Yes, the diagonals of a rectangle bisect each other.

Front

A parallelogram is a quadrilateral.

Back

Always. A parallelogram is defined as a four-sided figure (quadrilateral) with opposite sides that are parallel.

Front

What is the sum of the interior angles of a rectangle?

Back

The sum of the interior angles of a rectangle is 360 degrees.

Front

What are the properties of opposite sides in a parallelogram?

Back

In a parallelogram, opposite sides are equal in length.

Front

What is the relationship between the angles of a rectangle?

Back

All angles in a rectangle are right angles (90 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 110 degrees each.

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2(length + width).

Front

How do you find the length of the diagonal of a rectangle?

Back

Use the Pythagorean theorem: Diagonal = √(length² + width²).

Front

What is a defining characteristic of rectangles compared to other parallelograms?

Back

Rectangles have four right angles.
