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?
