Students will discover the relationships between a midsegment of a triangle and its third side.
Before the Activity
Students should be familiar with the angle relationships formed when parallel lines are cut by a transversal. Students should also be familiar with opening and turning pages in a TI-Nspire document.
Students who are not familiar with constructing and manipulating figures in a Graphs & Geometry page of TI-Nspire will need more teacher-led instruction than those who are. See Exploring Midsegments of a Triangle.doc for step-by-step instructions.
