Exterior Angle Formed by extending one of teh sides of the a triangle. Remote Interior Angle Two angles inside the triangle and opposite the exterior angle. Altitude A perpendicular segment from a vertex of a triangle to the line that contains the opposite side. Median A segment that connects a vertex of a triangle to the midpoint of the opposite side.
