Reflections In your own words, write the meaning of each vocabulary term. reflection "mitror" or "fippe line of reflection image line you reflect over glide reflection translation followed by a reflection reflection symmetry drawing the Same on the other side line of symmetry a line drawn to split an object into two equal parts Core Concepts Reflections A reflection is a transformation that uses a line like a mirror to reflect a figure. The mirror line is called the line of reflection. A reflection in a line maps every point P in the plane to a point P', so that for each point on of the following properties is true. If P is not m, then m is the perpendicular bisector of PP', or If P is on m, then P P Switch Sides P point P not on m on the Sare spot point Pon m A BB A Core Concepts Coordinate Rules for Reflections If (a, b) is reflected in the x-axis, then its image is the point (a, b). opposite If (a, b) is reflected in the line then its image is the point (b, a). y=x flipped If (a, b) is reflected in the y-axis, then its image is the point (a, b). 1 opposite If (a, b) is reflected in the line then its image is the point (-b, y = -x, -a). flipped and opposite w Postulate 4.2 Reflection Postulate A reflection is a rigid motion. everything has to be the Same -Shape -angles -size
