Midsegments of Triangles
1. Construct a triangle ABC using the polygon tool.
2. Use the midpoint tool to construct the midpoint of the sides (AB and AC).
3. Draw a line segment between the two midpoints.
4. Use the angle tool to measure all the angles of the two triangles formed.
-What do you notice about the angles?
-Does that tell us anything about lines?
5. Move the points around to see what happens to the angles.
-Do your answers from 4 still make sense?
-Are the two triangles similar? How do you know?
