Question

explore the properties of rotation by following these steps

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

pa = 4 ⇒ 6.1 units
pa = 4 ⇒ 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 point $B$ and its image $B'$ with center of rotation $P$, we have $PB = PB'$. You need to use the ruler shown in the image to measure the length of $PB$.

Step2: Measure the length

Use the ruler to find the length of $PB$. Let's assume after measurement, $PB = 5.3$ units. Then $PB'=5.3$ units.

Answer:

$PB = 5.3$; $PB' = 5.3$ (actual values depend on measurement with the ruler in the image)
