given a point on a geometric figure (1,2), what is the new poibnt when the point is rotated clockwise about the origin 90 degrees
To rotate a point clockwise about the origin by 90 degrees, we can use the following rotation matrix:
[ 0 1 ]
[-1 0 ]
By multiplying the rotation matrix with the given point (1, 2), we can find the new point.
|0 1 | |1| |1|
|-1 0| × |2| = |-2|
Therefore, the new point after rotating (1, 2) clockwise about the origin by 90 degrees is (-2, 1).
