Layla tried to define a rotation. For the center point C, the image C' is at the same point as C.
For a point P that is not at C, a counterclockwise rotation of 0 about point C creates point P'
P, prime, such that m\angle PCP'=m∠PCP =θm
What mistake did Layla make in her definition of a rotation?
Choose 1

(Choice A)
A
Layla needed to include the distance between each point PPP and its image P'P
′
P, prime.

(Choice B)
B
CPCPC, P must be perpendicular to CP'CP
′
C, P, prime.

(Choice C)
C
The lengths of \overline{CP}
CP
start overline, C, P, end overline and \overline{CP'}
CP
′

start overline, C, P, prime, end overline must be equal.

(Choice D, Checked)
D
Layla did not make a mistake.
