A line segment has endpoints (2, -1) and (5, -4) What are the new endpoints after rotating the segment 90° clockwise

Answer 1

To rotate a point (x, y) 90° clockwise, we can use the following formula:

x' = y
y' = -x

Applying this formula to the first endpoint (2, -1):

x1' = -1
y1' = -2

Similarly, applying the formula to the second endpoint (5, -4):

x2' = -4
y2' = -5

Therefore, the new endpoints after rotating the segment 90° clockwise are (-1, -2) and (-4, -5).
