Question

Which transformation Rotates a figure 180° clockwise about the origin?

a. (X,Y) ➔ (-X,Y)
b. (X,Y) ➔(-X, -Y)
c. (X,Y) ➔ (Y, -X)
d. (X,Y) ➔(-Y, X)

Answer 1

The answer will be B.

Remember the rules (clockwise):
90° = (x,y) -> (y,-x)
180° = (x,y) -> (-x,-y)
270° = (x,y) -> (-y,x)

Answer 2

answer is b X,y to -X,-y

Step-by-step explanation:

The rule for a rotation by 180° about the origin is (x,y)→(−x,−y) .
