Properties of Scale Change #3

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.

Check all that apply

True or False

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

Check all that apply

True or False

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

Check all that apply

True or False

Under a scale change, the ratio of any corresponding pair of image sides lengths and pre-image side lengths will NOT always equal the scale factor.

Check all that apply
