The line drawn from the midpoint of one side of a triangle parallel to another side bisects the third side.

Using Theorem 6.1, prove that a line drawn through the mid-point of one side of a triangle parallel to another side bisects the third side. (Recall that you have proved it in Class IX).

Prove using similar triangles, that a line drawn through the mid-point of one side of a triangle parallel to another side, bisects the third side.

Theorem 8.10 : The line drawn through the mid-point of one side of a triangle, parallel to another side bisects the third side.

The line drawn through the mid-point of one side of a triangle, parallel to another side, intersects the third side at its mid-point.

. The line drawn through the mid-point of one side of a triangle; parallel to another side; intersects the third side at its mid-point.

The line joining the mid-points of two sides of a triangle is parallel to the third side.

Prove that the line segment joining the mid points of two sides of a triangle is parallel to its third side.
