Triangle Midsegment Properties
Draggable demonstration of the midsegments of a triangle forming four congruent triangles
* Drag vertex C around.
1) What do you notice about the length of line segment ED compared to line segment BC?
* Drag vertex A around.
2) What do you notice about the length of line segment EF compared to line segment AC?
* Drag vertex B around.
3) What do you notice about the length of line segment DF compared to line segment AB?
A midsegment is the line segment connecting the midpoints of two sides of a triangle. The blue lines represent the midsegments of the triangle.
4) What general conclusion could you make about the midsegment of the triangle compared to the third side of the triangle?
