Question

If Pentagon ABCDE is rotated 180° around the origin to create Pentagon A'B'C'D'E', what is the ordered pair of point D'?

A) (−1,2)
B) (2,1)
C) (1,−2)
D) (−2,−1)

Answer 1

To find the ordered pair of point D', we need to rotate the point D using a 180° rotation around the origin, resulting in the coordinates (-x,-y).

Step-by-step explanation:

To find the ordered pair of point D', we need to rotate the point D using a 180° rotation around the origin. Let's say the coordinates of point D are (x,y). To rotate a point (x,y) by 180°, we can use the formula (-x,-y). So, the coordinates of point D' would be (-x,-y). Since we don't know the specific coordinates of point D, we cannot determine the exact ordered pair of point D'.
