### Geometry7.4 Translation

 Translation Mapping: A mapping of a plane in which each point of the plane moves in the same direction by the segments, all congruent to a given segment (equal distance) is called a translation. Translation moves every point of a figure the same distance in the same direction.   Examples: Find the coordinates of the image of (2,7), under the translation defined by (x,y) ® (x+2, y+1). T(x,y) ® (x+2, y+1). T(2,7) ® (2+2, 7+1). The coordinates of the image is (4,8) A quadrilateral has vertices A(-4,3), B(-2,4), C(-1,1) and D(-3,1). Find the coordinates of the image after translation (x,y) ® (x+5,y-2). (x,y) ® (x+2, y+1). A(-4,3) ® (1, 1) B(-2,4) ® (3, 2) C(-1,1) ® (4, -1) D(-3,1) ® (2, -1) Directions: Choose the correct answer. Also write at least 5 examples of your own. Name: ___________________Date:___________________
