What is the 90 degree clockwise rotation of segment AB about the origin? coordinates:...
1 Answer | add yours
On 90 degree clockwise rotation of a point in a coordinate plane, the x-coordinate of the resultant point is the y-coordinate of the original point, and the y-coordinate of the resultant point is opposite the x-coordinate of the original point.
This transformation can be described as: (x,y)->(y,-x)
On a similar line, the rotated coordinates of points A(-2,-1) and B(-4,-2 ) would be C(-1,2) and D(-2,4).
Therefore, your solution is correct!
