Question

3.Consider this dilation. (a)Is the image of the dilation a reduction or an enlargement of the original figure? Explain. (b)What is the scale factor? Explain.

Answer 1

a)

Image VMS is reduced to image M'V'S'.

b) the scale factor is 2/3

M(-3,3)

Multiply -3 and 3 with 2/3 your result = -2 and 2.

Scale factor for coordinate M = (-3,3) andN = (-2,2)

Since it is reduction, -2/-3 or 2/3

Therefore, scale factor = 2/3
