Given point A(2, 6) on the triangle, where would the new point on the triangle be after a rotation of 90 degrees counterclockwise?

To find the new point on the triangle after a rotation of 90 degrees counterclockwise, we can use the rotation formula.

The rotation formula for a point (x, y) about the origin by 90 degrees counterclockwise is:
(x', y') = (-y, x)

In this case, the original point is A(2, 6).
Using the rotation formula,
A' = (-6, 2)

Therefore, the new point on the triangle after a rotation of 90 degrees counterclockwise is (-6, 2).
