Copying a Triangle
1. Create a line below the original triangle (you can zoom out with the touch pad if you need more space)
2. Find the "compass" feature -- it will be underneath the "circle" tab. Using the "compass" feature, copy the length of BC and create a circle on point D with it.
3. Using the "point" button, label the intersection of your line and the circle. This segment DF will be congruent to segment BC.
4. Using the "compass" feature once again, copy the length of BA, and paste that length onto point D.
5. Do the process above again, but this time, copy the length of CA and paste that length onto point F. Find the intersection of your last two circles, and label a "point" on it.
6. Use the "polygon" button to create triangle DFG.
1. What is the advantage that a compass has over a ruler?
2. What were we really doing with the compass feature?
3. What Postulate or Theorem did we use to do this?
