Reflection

Reflection
If P' is the reflection of P in a line l then the line divides the line PP' in two equal halves or in other words l is perpendicular bisector of PP'.
Reflection in x-axis
If a point P(a,b) is reflected in x-axis, then its image is P'(a,-b).
Reflection in y-axis
If a point P(a,b) is reflected in y-axis, then its image is P'(-a,b).
