A reflection is a transformation in which the object is moved to the other side of a line or point without the distance from the line or point or the size of the object being changed. First, connect two corresponding points(For example: C and C') with a line. Find the perpendicular bisector of the line by drawing two circles(one coming from point C and the other coming from C'). Each circle should go a little more than halfway through the line. Draw a line going through both points where the circles meet. The point where the two lines meet is the point of reflection.
