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 the 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 around the origin
• 90 degree rotation around point b
• reflection fo the triangle across the x axis
