Question

Find the coordinate of C after a rotation of 180° about the (-1, 1).

Answer 1

the coordinate of c after a rotation of 180° is ( 1,-1 )

Explanation:

Here are the rotation rules:

90° clockwise rotation: (x,y) becomes (y,-x)

90° counterclockwise rotation: (x,y) becomes (-y,x)

180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
