Draw a graph for the original figure and its dilated image. Check whether the dilation is a similarity transformation or not.
Answer to Problem 15PPS
The dilation is a similarity transformation.
Explanation of Solution
Given:
The given vertices are
Calculation:
The graph for the given points
Find the distance (using distance formula) of corresponding sides and find the ratio.
From the above result, the length of two sides are proportional and the angles between them are congruent.
By the use of
Hence the dilation is a similarity transformation.
