Investigating Lengths of Segments in a Triangle

Pupils explore the midsegment of a triangle in the geometry lesson. They draw and measure the segment joining the midpoints of the two sides of a triangle and compare its length to the length of the third side of the triangle. The dynamic nature of Cabri Jr. allows learners to manipulate the figures as they make and test conjectures relating to the length of the midsegment.
