Dilations Coordinate Plane Review

Figures A, B, C, and D are drawn. The center of dilation is point E. Which of the following figures are similar to figure A? Choose all correct answers.

Triangle EFG is drawn on the coordinate plane. The triangle is dilated by a scale factor of 1/3, with the center of dilation at the origin, to form triangle E'F'G'. Then, triangle E'F'G' is translated 3 units to the right to form triangle E''F''G''. What is the coordinate of E'' ?

When a dilation has a scale factor greater than one, the dilation is an enlargement.

When the scale factor of a dilation is between 0 and 1, the dilation is a reduction (shrinks).

Point B (-10,-6) is dilated with a scale factor of 1/2 and the center of dilation at the origin. What are the coordinated of B'?

The point (8, 12) was dilated to become point (2, 3). What was the scale factor?

The points of $$\Delta abc$$ is graphed. The figure is dilated with a scale factor of 2 and the center of dilation at the origin. Plot all the points of $$\Delta a'b'c'$$ after performing the dilation.
