Which statement explains the relationship of sides ba and b'a' after rectangle badc has been rotated 90° clockwise about the origin? side b'a' has a slope of −1 and is perpendicular to side ba. side b'a' has a slope of 1 and is parallel to side ba. side b'a' has a slope of 1 and is perpendicular to side ba. side b'a' has a slope of −1 and is parallel to side ba.

Option A. Side B'A' has a slope of −1 and is perpendicular to side BA.

Step-by-step explanation:

The rotation by the angle 90° clockwise about the origin has the rule:

So the vertices A, B, C and D have images

Find the slope of the line B'A':

Find the slope of the line BA:

Since lines A'B' and AB are perpendicular.
