Question

1. how would the first image transform to become the second image?

rotation on a fixed point
horizontal reflection
clockwise rotation
vertical reflection

Explanation:

A horizontal reflection (also known as a reflection over a horizontal line) flips an image over a horizontal axis. In this case, the first image (green) is flipped over a horizontal line to get the second image (blue). A rotation (whether clock - wise or on a fixed point) would change the orientation in a rotational manner (like turning the shape around a center), which is not the case here. A vertical reflection would flip over a vertical line, which also does not match the transformation from the first to the second image.

Answer:

horizontal reflection
