Triangle A B C is graphed. Point A (negative 4, comma 2). Point B (0, comma 3). Point C (negative 3, comma 6). Connect the points with lines to form a triangle.Copy at right on graph paper.  

  1. Rotate   counter-clockwise () about the origin to create . Name the coordinates of .

  2. Reflect across the vertical line to create . Name the coordinates of the vertices.

  3. Translate so that is at . Name the coordinates of .

See problem 1-60 and the Math Notes box for Lesson 1.2.2 (page 37 in the student text) for help with rotations.
