To rotate a point counterclockwise by 90 degrees, we can use the following formula:
new_x = -old_y
new_y = old_x
Using this formula, we can find the new coordinates of point A.
new_x = -4
new_y = 2
Therefore, the new point after rotating the triangle 90 degrees counterclockwise is (-4, 2).
Given point A (2, 4) on the triangle in Quadrant I, where is the new point if the triangle is rotated 90 degrees counterclockwise?
(1 point)
