## Introduction

If you are a mathematics student or a teacher, you might have come across the properties of parallelograms answer key milliken publishing company. This resource is designed to help students understand the properties of parallelograms and how they can be used to solve mathematical problems.

## What is a Parallelogram?

A parallelogram is a four-sided polygon with two pairs of parallel sides. The opposite sides of a parallelogram are congruent, and the opposite angles are also congruent. The sum of the interior angles of a parallelogram is always 360 degrees.

## Properties of Parallelograms

There are several properties of parallelograms that are essential to solving mathematical problems. These properties include:

### Opposite Sides are Congruent

The opposite sides of a parallelogram are congruent. This means that if we take any two sides of a parallelogram, they will be of equal length.

### Opposite Angles are Congruent

The opposite angles of a parallelogram are congruent. This means that if we take any two angles that are opposite each other in a parallelogram, they will be of equal measure.

### Consecutive Angles are Supplementary

The consecutive angles of a parallelogram are supplementary. This means that if we take any two adjacent angles in a parallelogram, their sum will be 180 degrees.

### Diagonals Bisect Each Other

The diagonals of a parallelogram bisect each other. This means that the point where the two diagonals intersect will divide each diagonal into two equal parts.

### Area of a Parallelogram

The area of a parallelogram can be calculated by multiplying the base by the height. The base is any one of the sides of the parallelogram, and the height is the perpendicular distance between the base and the opposite side.

## Application of Parallelogram Properties

The properties of parallelograms can be used to solve a variety of mathematical problems. For example, if we know the length of two sides of a parallelogram and the measure of one angle, we can use the properties of parallelograms to find the length of the other two sides and the measure of the other three angles.

## Conclusion

In conclusion, the properties of parallelograms answer key milliken publishing company is a valuable resource for students and teachers alike. Understanding the properties of parallelograms is essential for solving mathematical problems and can be applied in a variety of real-life situations.
