Midpoint Theorem: The line segment joining the midpoints of any two sides of a triangle is parallel to the third side and
equal to half of it.
Converse of Midpoint Theorem: The straight line drawn through the middle point of one side of a triangle parallel to another side bisects the third side.
Equal Intercept Theorem: If there are three parallel lines, and the intercepts made by them on one transversal are equal, then the intercepts on any other transversal are also equal.
