Question

explore the properties of rotation by following these steps.
△abc about point p.

1. make a conjecture

what do you think is the measure of the angle of rotation? 45

1. the diagram shows two corresponding vertices connected to the center of rotation. use the protractor to measure it.

m∠apa =

Explanation:

Step1: Use a protractor

Place the protractor's center at point P and align its base - line with one of the rays (either PA or PA').

Step2: Read the measurement

Read the angle where the other ray (PA' or PA) intersects the protractor's scale.

Answer:

45 (assuming the conjecture in step 2 is correct and the actual measurement matches the conjecture. If you measure it with a real protractor, the value may vary slightly due to measurement error, but based on the conjecture and the nature of the problem, the answer is likely 45)
