Triangle QRS was dilated using the dilation rule DP,4.
1 answer:
Answer:
<h2>PR' = 12units</h2>Step-by-step explanation:
When a figure is dilated, it means there is a transformation carried out on the figure. The dilation may cause the figure to increase or reduce in size depending on the dilation factor.
<u>If the dilation factor of an object is greater than 1, the resulting image will be a magnified image otherwise, it will be a diminished image. </u>
Given the dilation factor in question DP to be 4, this means that the new image formed will be 4times bigger than the original.
According to the diagram, side PR = 3, if this is dilated by factor of 4, the side PR' will be equal to 4*PR
PR' = 4 * PR
PR' = 4*3
PR' = 12units
