Question

Which sequence of transformations confirms congruence by mapping shape I onto shape II?

A.
a reflection across the x-axis and then a translation 15 units left
B.
a 90° clockwise rotation about the origin and then a translation 25 units up
C.
a 90° counterclockwise rotation about the origin and then a translation 10 units left
D.
a 180° rotation about the origin and then a translation 10 units right

Answer 1

B

Explanation:

To confirm congruence, you need a sequence of rigid motions that maps one shape onto the other.
