Jack tried to define a rotation.For the center point CCC, the image C'C ′ C, prime is at the same point as CCC. For a point PPP
that is not at CCC, a rotation of \thetaθtheta about point CCC creates point P'P ′ P, prime, such that CP=CP'CP=CP C, P, equals, C, P, prime and m\angle PCP'=\thetam∠PCP ′=θm, angle, P, C, P, prime, equals, theta. What mistake did Jack make in his definition of a rotation?
A
Jack needed to include the direction of the rotation.
(Choice B)
B
m\angle CPP'm∠CPP
′
m, angle, C, P, P, prime must equal \thetaθtheta.
(Choice C)
C
Point CCC must be the midpoint of PP'PP
′
P, P, prime.
(Choice D)
D
Jack did not make a mistake.
