Given:
Plot the image of figure ABCDEFGH after a dilation with scale factor 3. One of the side has been plotted.
Required:
Plot image after dilation of scale factor 3.
Step-by-step explanation:
A dilation is a transformation which preserves the shape and orientation of the figure, but changes its size. The scale factor of a dilation is the factor by which each linear measure of the figure (for example, a side length) is multiplied.
We will consider distance between two points as 1 unit.
So, distance between B and C is 7 unit. After dilation by scale factor 3, length of BC become 21 unit.
Similarly,
Length of AB change from 2 unit to 6 unit.
Length of AH change from 4 unit to 12 unit.
Length of GH change from 3 unit to 9 unit.
Length of GF change to 1 unit to 3 unit.
Length of FE change from 4 unit to 12 unit.
Length of DE change from 2 unit to 6 unit.
Length of CD change from 1 unit to 3 unit.
Answer:
Hence, we can draw figure from these measurements.
