Reflections are almost everywhere. When you go swimming and you see your self in the water, when you are on a lake and you see the trees reflection in the water. When you get up in the morning and you are brushing your teeth you will probably see your reflection in the mirror. Reflections do not have to be of images they can also be lines or points. Reflections have to do with your everyday life and needed to be understood.

The reflections of points are the most basic of the reflections. They are the basis of all reflections, the reflections of lines and images can be simplified into points to make them easier to reflect. Reflecting points is very simple once you understand the different parts. In the graph below point A is reflected over the line "M." In this graph M is called the reflecting line, or the line of reflection. The Line of Reflection is the line in which the preimage is reflected. The line segment that is connecting the preimage (A) and the image (A) is always going to be a perpendicular bisector to the Line of
reflection.
a reflection of a line is just a series of points that are reflected. If you know how to reflect a point then you will know how to reflect a line. The reflection of a line is similar to a ball , with out spin, bouncing off of a wall. This is called the bouncing off of surfaces theorem. If the ball has no spin then it will bounce off at the same direction that it hit the wall. The Bouncing off of Surfaces Theorem states that when a ball is rolled with out spin against a wall, it bounces off of the wall and travels in an exact reflection image of the path the ball took to hit the wall. In the diagram above the angles I and R always have an equal value. The angle I is referred to as the Angle of Incidence, and the angle R is referred to as the Angle of Reflection. The bouncing off of surfaces theorem doesnt apply only to a ball bouncing off of a wall, It can also apply to light rays bouncing off of a mirror.
