Midsegment

Pronunciation: /ˈmɪdˌsɛg.mənt/ Explain

A midsegment of a triangle is a line segment joining the midpoints of two of sides of the triangle. Since every triangle has three sides, each triangle has three midsegments. A midsegment is parallel to the third side, and is half the length of the third side.

Click on the blue points and drag them to change the figure. Check the checkboxes to see the midsegments. Under what conditions is the length of a midsegment zero?
