Lesson 2.1 y, symbolically, numerically, and graphically. Translations Learning Goal: I can develop definitions of translations in terms of angles, perpendicular lines, parallel lines, and line segments. (Standard G-CO.A.4) EXPLORE Exploring Translations L4L Math Resources http://Bit.ly/L4LMath Read Explore in your textbook (Lesson 2.1) and complete the following. Show all your work. A translation slides all points of a figure the same distance in the same direction. You can use tracing paper to model translating a triangle. A First, draw a triangle on lined paper. Label the vertices A, B, and C. Then draw a line segment XY. An example of what your drawing may look like is shown. Use tracing paper to draw a copy of triangle ABC. Then copy XY so that the point X is on top of point A. Label the point made from Y as A Using the same piece of tracing paper, place A' on A and draw a copy of AABC. Label the corresponding vertices B' and C. An example of what your drawing may look like is shown. Use a ruler to draw line segments from each vertex of the preimage to the corresponding vertex on the new image.
