## Instructions:

The applet below encourages a more detailed exploration of scale change properties. Use the slider to perform a scale change. Check the boxes within the applet to verify each conjecture about the scale change properties.
Important - Make sure you click the box next to

**Show Lines (AB and image)**.## True or False

Under a scale change, corresponding angle measures are **proportional**.

## True or False

Under a scale change, pre-image side lengths are **multiplied** by the scale factor to produce image side lengths.

## True or False

Under a scale change, any pair of corresponding pre-image sides and images sides are **parallel**.

## True or False

Under a scale change, the **ratio **of any corresponding pair of** image sides lengths and pre-image side lengths** will always equal the scale factor.
