Question

answer attempt 1 out of 3 a reflection over the y - axis a clockwise rotation of 270° about the origin a reflection over the x - axis a clockwise rotation of 90° about the origin

Explanation:

Step1: Recall transformation rules

For a point $(x,y)$: Reflection over y - axis gives $(-x,y)$; reflection over x - axis gives $(x, - y)$; clock - wise rotation of 90° about origin gives $(y,-x)$; clock - wise rotation of 270° about origin gives $(-y,x)$.

Step2: Analyze the transformation

Let's assume a general point on triangle A and see its transformation to triangle B. If we take a point on triangle A and consider a clock - wise rotation of 90° about the origin, the coordinates of the point change according to the rule $(x,y)\to(y, - x)$. This transformation maps triangle A to triangle B.

Answer:

A clockwise rotation of 90° about the origin
