Translating Figures Translation: move (SLIDE) all points of the original figure MCAS Review the same distance in the same direction. Key Concept Translation in the Coordinate Plane Transformations Words to translate a point along vector (a, b), add a to the x-coordinate and b to the P 1 - 2 + 7, 3 + 4) or ( 5 . 7) y-coordinate. Symbols ( xy) - (x+ ay+b) P 1 - 2 , 3 ) Example The image of P(-2. 3) translated along vector (7, 4) is P'(5, 7) Example #1 O Example #2 Ex. 1: Ex. 2: Graph ATUV with vertices Graph pentagon PENTA with T (-1, -4), U (6, 2), and vertices P (1, 0), E (2, 2), N ( 4, 1), V (5, -5) along the vector T(4, -1), and A (2, -2) along the ( - 3 , 2 ) . vector (-5, -1).
