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.[br][br]Important - Make sure you click the box next to [b]Show Lines (AB and image)[/b].[br]
Under a scale change, corresponding angle measures are [b]proportional[/b].
Under a scale change, pre-image side lengths are [b]multiplied[/b] by the scale factor to produce image side lengths.
Under a scale change, any pair of corresponding pre-image sides and images sides are [b]parallel[/b].
Under a scale change, the [b]ratio [/b]of any corresponding pair of[b] image sides lengths and pre-image side lengths[/b] will always equal the scale factor.
