Question

explore the properties of rotation by following these steps.

1. use the ruler to measure the length of these segments:

pa = 6.1 units
pa = 6.1 units

1. record the lengths of these segments:

pb = units
pb = units

Explanation:

Step1: Recall property of rotation

In a rotation, the distance from the center of rotation to a point and its image is the same. Since $PA = PA'=6.1$ units, for any point $B$ and its image $B'$ after rotation about point $P$, $PB = PB'$. You need to use the ruler to measure the length of $PB$ (and $PB'$ which will be the same value).

Answer:

Use a ruler to measure the length of $PB$, and $PB'$ will have the same measured - length value.
