The coordinates of the image of ΔABC after the dilation are A' (6, 6), B'(12, 15) and C'(15, 6)
How to determine the coordinates of the image of ΔABC after the dilation
From the question, we have the following parameters that can be used in our computation:
The figure
Where, we have
A = (2, 2)
B = (4, 5)
C = (5, 2)
The transformation rule is given as
Dilation with center (0, 0) and a scale factor of 3
This means that
Image = 3 * points
So, we have
A' = (2, 2) * 3
B' = (4, 5) * 3
C' = (5, 2) * 3
Evaluate
A' = (6, 6)
B' = (12, 15)
C' = (15, 6)
Hence, the coordinates of the image are A' (6, 6), B'(12, 15) and C'(15, 6)
