Answer 1

The vertices of the given figure are

A(1, -1), B(5.-6), and C(1, - 6).

For a 90 counterclockwise about the origin, a coordinate, (x, y) would be (- y, x)

This means that after the 90 degrees rotation,

coordinate A would be (- - 1, 1) = (1, 1)

Coordinate B would be (- - 6, 5) = (6, 5)

Coordinate C would be (- - 6, 1) = (6, 1)
