1. True or False: When point E (2, -5) is rotated 180° about the origin, and becomes Point E’ (-2, 5).
2. Under a dilation, triangle XYZ where X(6, 3), Y(-2, 4), and Z(10, -2) becomes triangle X’Y’Z’ where X’(12, 6), Y’(-4, 8), and Z’(20, -4). What is the scale factor for this dilation?
-2
2
1/2
-1/2
3. Triangle XYZ where X(7, 2), Y(-3, 8), and Z(-4, 6) is dilated with a scale factor of -4. Where is the dilation located?
