Answer:

A reflection is a transformation that maps point P in a figure, over a line AB, such that for point C at the intersection of AB and PP', PC = PC' and m∠ACP = 90°

Step-by-step explanation:

After the reflection of P across the line AB, P' is created, where PP' and AB are perpendicular. Given that point C is at the intersection of the lines, then m∠ACP = 90° and PC = PC'.
