Question

prallelogram abcd with vertices A(6,8) b(10,9) c(9,3) d(5,2) 90° counterclockwise rotation about p(4,1)

Answer 1

Given the vertices of parallelogram ABCD:

A(6, 8), B(10, 9), C(9, 3), D(5, 4)

Center of rotation P(4, 1)

After a rotation of 90 degrees counterclockwise, the coordinates (x, y) changes to (-y, x).

(x, y) ==> (-y, x)
