Given a point (1, 2)
on a geometric figure, what is the new point when the figure is rotated counterclockwise about the origin 90 degrees?(1 point)
When a point is rotated counterclockwise about the origin by 90 degrees, its new coordinates are obtained by switching the x-coordinate with the negative of the y-coordinate.
In this case, the original point is (1, 2). Switching the x-coordinate with the negative of the y-coordinate, we get:
New x-coordinate = -2
New y-coordinate = 1
Therefore, the new point after rotating counterclockwise about the origin by 90 degrees is (-2, 1).
