# Parallelograms: Quick Investigation

## Here, we have a parallelogram. Interact with this app for a minute. Be sure to move the vertices (corners) of this parallelogram around. Then answer the question that follows.

What does the animation above suggest?
**Opposite sides of a parallelogram are __________________________ .**

## Here, we have a parallelogram. Interact with this app for a minute. Be sure to move the vertices (corners) of this parallelogram around. Then answer the question that follows.

Any 2 interior angles of a parallelogram that are not opposite angles are called **consecutive angles***. *In the animation above, the two different colored angles are consecutive angles. What can we conclude here?
**Consecutive angles of a parallelogram are __________________________ .**

A diagonal of a parallelogram is a segment that connects one vertex (corner) to its opposite vertex. What can we conclude about the diagonals of a parallelogram?

Does any diagonal of a parallelogram serve as a line of symmetry?
