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) Responses (−4, 2) left parenthesis negative 4 comma 2 right parenthesis (4,−2) left parenthesis 4 comma negative 2 right parenthesis (−2,−4) left parenthesis negative 2 comma negative 4 right parenthesis (−4,−2)

Question

Answer 1

To rotate a point counterclockwise by 90 degrees, we switch the x-coordinate with the y-coordinate and negate the new x-coordinate.

In this case, the point A (2, 4) becomes (-4, 2).
So the new point after rotating the triangle 90 degrees counterclockwise is (-4, 2).
