Students will be able to
- understand and prove that the straight line segment passing through the midpoint of one side of a triangle that is also parallel to another side of the triangle bisects the third side of the triangle,
- understand and prove that the straight line segment connecting the midpoints of two sides of a triangle is parallel to the other side and is half its length,
- use the triangle midsegment theorems to solve problems,
- prove geometric properties using the triangle midsegment theorems.
