If XYZ is dilated by a scale factor of 3 about point Y, which of the following is true about A’ Y’? a) A’Y’ is perpendicular to AY
b) A’Y’ is parallel to AY
c) A’Y’ passes through the center of dilation
d) A’Y’ intersects with point X’

c) A’Y’ passes through the center of dilation

Step-by-step explanation:

Dilation is a type of transformation that can be used to resize the dimensions of a given figure. It does not affect the shape of the given figure, but retains its initial shape.

In the given question, dilating XYZ by a scale factor of 3 implies multiplying each side of the triangle XYZ by 3 about Y. This transformation would yield triangle X'Y'Z' and A'Y'.

Since the transformation is about point Y, A'Y' would pass through the center of dilation.
