Choose three non-collinear points on the coordinate plane, making sure none of your points is the origin. On a sheet of paper, graph the three points and draw line segments to connect the points and make a triangle. Label the vertices of the triangle A, B, and C. Now describe the new coordinates of points A, B, and C after the following transformations: Translation of point A to the origin
90° rotation around point B
Reflection of the triangle across the x-axis
