Keep the triangle that you created in part A. You will now copy the triangle to a different location on the grid using three of
its sides:
In a different place on the grid, draw a new line segment that is parallel to and has the same length as AB. Label this segment DE.
Next, copy AC and BC . A reliable way to do this is to draw a circle centered on each endpoint of your new line segment. Make the radius of each circle equal to each of the lengths of the two remaining line segments on the original triangle. One of the intersection points of the two circles marks the third vertex of your new triangle. Place a point on the intersection, and label the point F.
Finish copying the triangle by drawing a polygon through the three points that you've established.
You should now have two triangles on the grid. What do you notice about the two triangles in terms of their size and shape?
