ven point A (2, 4) on the triangle in Quadrant I, where is the new point if the triangle is rotated 90 degrees counterclockwise?

Answer 1

To rotate a point counterclockwise by 90 degrees, you can swap the x and y coordinates and negate the new x coordinate.

Given point A (2, 4), the new point after rotating counterclockwise by 90 degrees would be:

New point A' = (-4, 2)

The y-coordinate 4 becomes the new x-coordinate -4, and the x-coordinate 2 becomes the new y-coordinate 2.
