Question

1. from unit 1, lesson 7

describe a rigid transformation that takes polygon a to polygon b.

Explanation:

Step1: Observe x - coordinate change

The x - coordinates of corresponding points of Polygon A and Polygon B change by 7 units. For example, a point on Polygon A with x - coordinate of - 5 has a corresponding point on Polygon B with x - coordinate of 2. $2-(-5)=7$.

Step2: Observe y - coordinate change

The y - coordinates of corresponding points of Polygon A and Polygon B change by - 5 units. For example, a point on Polygon A with y - coordinate of 3 has a corresponding point on Polygon B with y - coordinate of - 2. $-2 - 3=-5$.

Answer:

A translation 7 units to the right and 5 units down.
