Answer: S' (10,2), R' (1,2), T' (1,8)
Explanation:
Rotating an object around the origin means that the focal point will be the center of the graph (0,0) and from there the rotation will occur.
Rules
Counterclockwise:
Rotation 90→(x,y) → (-y,x)
Rotation 180→(x,y) → (-x,-y)
Rotation270→(x,y) → (y,-x)
Clockwise:
Rotation 270→(x,y) → (-y,x)
Rotation 180→(x,y) → (-x,-y)
Rotation 90→(x,y) → (y,-x)
Solve:
S (-2,10)→ S' (10,2)
R (-2,1)→ R' (1,2)
T (-8,1)→ T' (1,8)
