Question

triangle abc is rotated to create the image abc. which rule describes the transformation? (x, y)→(x, -y) (x, y)→(y, x) (x, y)→(-x, -y) (x, y)→(-y, -x)

Explanation:

Step1: Recall rotation rules

In a 180 - degree rotation about the origin, the rule for transforming a point $(x,y)$ is $(x,y)\to(-x,-y)$. By observing the graph, we can see that triangle ABC is rotated 180 degrees about the origin to get triangle A'B'C'.

Answer:

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