  1. Below is a graph of Triangle ABC, then a translation (left 4), then a reflection (across the x-axis), then a rotation (90 degrees counter-clockwise). Verify these are rigid motions by checkin (.ggb)
     
  2. Draw Triangle ABC with points A(1,2), B(5,1), and C(4,2). Then draw Triangle DEF with points D(2,4), E(10,2), and F(8,4). (.ggb)
     
  3. Use this picture to answer the questions that follow. (.ggb)
     
  4. Draw Triangle A'B'C' after a dilation using a Scale Factor of 3. (that means, find the coordinates for points A,B, and C, then multiply the x and y coordiantes by 3). (.ggb)
     
  5. Use this picture to answer the questions that follow. (.ggb)
     
  6. Use this picture to answer the questions that follow. (.ggb)
