Dilating a triangle changes the size of the triangle but does not change its shape. true or false?
____ [38]
<h3><u>Answer;</u></h3>

The correct answer<em> </em><em><u>is true</u></em>

<h3><u>Explanation;</u></h3>
  • <u>Dilation</u> is a type of transformation which stretches and reduces the size of the original figure.
  • A dilation has a center of dilation and a dilation scale factor. If the scale factor is less than one then the original size will shrink, and if the scale factor is greater than one then the figure will increase in size.
  • Dilation transformation does not alter the shape of a figure but  alters the size by making it bigger or smaller.
