MAFS.912.G-CO.2.6 A rigid motion, J, of the plane takes a point, A, as input and gives C as
output (i. e., J(A) = C). Similarly, J(B) = D for input point B and output
point D. Jerry claims that knowing nothing else about J, we can be sure
that AC = BD because rigid motions preserve distance.
A. Show that Jerry's claim is incorrect by giving a counterexample (hint:
a counterexample would be a specific rigid motion and four points A,
B, C, and D in the plane such that the motion takes A to C and B to
D, yet AC # BD).
