In triangle ABC, let P and Q be the midpoints of sides AB and AC, respectively. By the Midpoint Theorem, the line segment connecting the midpoints of two sides of a triangle is parallel to the third side and half its length. Therefore, since PQ connects the midpoints P and Q, it follows that PQ is parallel to side BC of triangle ABC. This establishes that PQ is parallel to BC, as required.
The midsegments of a triangle are the midpoints of the three sides of the triangle.
Theorem: The line segment connecting the midpoints of two sides of a triangle is parallel to the third side and is congruent to one half of the third side. Proof: Consider the triangle ABC with the midpoint of AB labelled M. Now construct a line through M parallel to BC.

36. If the length of the line segment joining the midpoints of two sides of an equilateral triangle is 6 the perimeter of the triangle is 36.

I think it's called a vertice, and there are 3 vertices in a triangle. -- WRONGCORRECTION- it is NOT called a vertice. A vertice is each angle point, there ARE three vertices in a triangle but they the point of each angle.Now, a segment connecting the midpoints of two sides of a triangle is called a mid-segment. There are three mid-segments in a triangle.Go here for more info* http://regentsprep.org/Regents/math/geometry/GP10/MidLineL.htm *
