Question

square efgh will be reflected over the y - axis. which figure correctly shows the image of square efgh after the reflection?

Explanation:

Step1: Recall reflection rule

When a point $(x,y)$ is reflected over the y - axis, the transformation rule is $(x,y)\to(-x,y)$.

Step2: Apply rule to square EFGH

Each vertex of square EFGH will have its x - coordinate negated while the y - coordinate remains the same.

Step3: Analyze options

Option B shows the correct reflection of square EFGH over the y - axis as all the x - coordinates of the vertices of the original square are negated and y - coordinates are unchanged.

Answer:

B.
