Lines *l* and *m *are perpendicular with point of intersection *P. *Can anyone help me to explain this and give a complete answer? I'm confused with this problem for my Geometry class.

I do not agree with Noah.

If you start with a point in the upper-right quadrant and rotate this point 180^{o}, this point will end in the lower-left quadrant.

However, if you reflect the original point over the line *m*, it will end in the upper-left quadrant.

If you picture a graphing plane with the original point being (5,2), rotating this point 180^{o}, it would end at (-5.-2).

If you reflect (5,2) in the y-axis, it would end at (-5,2).
