Question

classify whether each pair of figures appears to be a rigid motion or not a rigid motion. preimage image preimage image preimage image preimage image

Explanation:

Step1: Recall rigid - motion definition

A rigid motion preserves distance and angle measures.

Step2: Analyze first pair

The first pair of figures has the same shape and size, and corresponding distances and angles are equal. So it is a rigid motion.

Step3: Analyze second pair

The second pair has different shapes (the angles and side - length ratios are different), so it is not a rigid motion.

Step4: Analyze third pair

The third pair has the same shape and size, and corresponding distances and angles are equal. So it is a rigid motion.

Step5: Analyze fourth pair

The fourth pair has different shapes (the angles and side - length ratios are different), so it is not a rigid motion.

Answer:

First pair: Rigid motion
Second pair: Not a rigid motion
Third pair: Rigid motion
Fourth pair: Not a rigid motion
