A line that's 'normal' to the surface is perpendicular to the surface.

The angle of incidence is the angle between the normal and the light ray ARRIVING at the surface.

The angle of reflection is the angle between the normal and the light ray LEAVING the surface after it's reflected.

The law of reflection says these two angles are equal.

This is the same distance she covered traveling east. But she is 2 blocks north. From there she traveled a block south to the pizzeria and another block to her friends house. She covered the two block she had traveled north.
