Question

r.12 reflections and rotations: write the rule 2f8
rectangle defg is rotated 180° clockwise about the origin to produce rectangle d
write the rule for the rotation.
(x, y) → ( , )

Explanation:

Step1: Recall rotation rule

When a point $(x,y)$ is rotated 180 - degrees clockwise about the origin, the new - coordinates are obtained by changing the signs of both the $x$ and $y$ coordinates.

Step2: Write the rule

The rule for a 180 - degree clockwise rotation about the origin is $(x,y)\to(-x,-y)$.

Answer:

$(x,y)\to(-x,-y)$
