To rotate a point (x, y) counterclockwise by 90 degrees, we need to switch the x-coordinate with the negative of the y-coordinate and switch the y-coordinate with the x-coordinate.
Using this formula, we can find the new point if the triangle is rotated 90° counterclockwise:
New_x = -y = -4 = -4
New_y = x = 2
Therefore, the new point after the rotation is (-4, 2).
