Describe the effect of the dilation of the angle DEF with a scale factor of 4 and a center point of dilation at the origin (0,0) . Enter the option number of your response.
Option #1: After dilation, the lines are four times farther from the point of dilation. The angle measurement remains the same. Corresponding lines (rays) are parallel between the angle and the dilated angle. The resulting points are D′(−8,−16) , E′(8,4) , and F′(12,−12) .
Option #2: After dilation, the lines are four times farther from the point of dilation. The angle measurement remains the same. Corresponding lines (rays) are parallel between the angle and the dilated angle. The resulting points are D′(2,0) , E′(6,5) , and F′(7,1) .
Option #3: After dilation, the lines are four times closer to the point of dilation. The angle measurement remains the same. Corresponding lines (rays) are parallel between the angle and the dilated angle. The resulting points are D′(−12,−1) , E′(12,14) , and F′(34,−34) .

When we dilate angle DEF with a scale factor of 4 and center of dilation at the origin (0,0), the resulting points would be as follows:
- Point D'(x, y) = 4 * x-coordinate of D, 4 * y-coordinate of D
- Point E'(x, y) = 4 * x-coordinate of E, 4 * y-coordinate of E
- Point F'(x, y) = 4 * x-coordinate of F, 4 * y-coordinate of F
Given the original points D(2,-1), E(3,4), and F(-3,1):
- D'(x, y) = 4 * 2, 4 * (-1) = (8, -4)
- E'(x, y) = 4 * 3, 4 * 4 = (12, 16)
- F'(x, y) = 4 * (-3), 4 * 1 = (-12, 4)
Therefore, the correct transformation after dilation is that D' is at (8, -4), E' is at (12, 16), and F' is at (-12, 4).
I apologize for the confusion in my earlier responses. Thank you for your patience.
