Mrs. Rivas International Studies Charter School. Objective: To find reflection images of figures orientations When you reflect a figure, the shapes have opposite orientations. Two figures have opposite orientations if the corresponding vertices of the preimage and image read in opposite directions.

Mrs. Rivas International Studies Charter School. 1) Graph point P. P y = 1 2) Graph the line of reflection y = 1. P’P 3) Graph P’. P and its reflection image across the line of reflection must be equidistant from the line of reflection. P’ Py = 1P’ y = 1 P is 3 units above the line y = 1, so P’ must be 3 units below the line y = 1.

Mrs. Rivas International Studies Charter School. Triangle 2 Triangle 2 is the image of a reflection, so find the preimage and the line of reflection to write a rule. The preimage cannot be triangle 3 because Triangle 2 and Triangle 3 have the same orientation. Check Triangle 1 and 4 by drawing line segments that connect the corresponding vertices of Triangle 2. perpendicular bisector Line K is the perpendicular bisector of the segments joining corresponding vertices of Triangle 2 and Triangle 4.
