# Properties Of Parallelograms Answer Key Kuta Software

## What are Parallelograms?

Before we dive into the properties of parallelograms, let's first define what a parallelogram is. A parallelogram is a quadrilateral with two pairs of parallel sides.

## What are the Properties of Parallelograms?

There are several properties of parallelograms that we need to know. These properties include:

### Property 1: Opposite Sides are Parallel

In a parallelogram, opposite sides are parallel. This means that if we draw a line segment connecting two opposite corners of a parallelogram, the line will be parallel to the other two sides.

### Property 2: Opposite Sides are Congruent

Opposite sides of a parallelogram are also congruent. This means that the length of one side of a parallelogram is equal to the length of the opposite side.

### Property 3: Opposite Angles are Congruent

Another property of parallelograms is that opposite angles are congruent. This means that if we draw a diagonal line in a parallelogram, the two angles it creates are equal in measure.

### Property 4: Consecutive Angles are Supplementary

In a parallelogram, consecutive angles are supplementary. This means that the sum of two adjacent angles in a parallelogram is equal to 180 degrees.

### Property 5: Diagonals Bisect Each Other

The diagonals of a parallelogram bisect each other. This means that the point where the diagonals intersect is the midpoint of both diagonals.

## Why are these Properties Important?

Knowing these properties of parallelograms is important because they allow us to solve problems involving parallelograms. For example, if we know the length of one side of a parallelogram, we can use the fact that opposite sides are congruent to find the length of the opposite side. Similarly, if we know the measure of one angle in a parallelogram, we can use the fact that opposite angles are congruent to find the measure of the opposite angle.

## Conclusion

Parallelograms are important shapes that have several unique properties. By understanding these properties, we can solve problems involving parallelograms and gain a better understanding of geometry as a whole.
