'''The midpoint theorem''' states that if you connect the midpoints of two sides of a triangle then the resulting line segment will be parallel to the third side and have half of its length. The midpoint theorem generalizes to the [[intercept theorem]], where you rather than using midpoints partition both sides in the same ratio.
