The Midpoint Theorem connects the geometry of a triangle to the idea of parallel lines and proportional segments. The key insight is that when you connect the midpoints of two sides of a triangle, you create a line segment that's not only parallel to the third side, but also exactly half its length—a beautiful economy of structure that lets you prove similarity and solve problems without measuring angles.
