Defined, the triangle proportionality theorem states that if you draw a line parallel to one of the sides of a triangle that also crosses the other two sides, then that line will divide the two sides in a proportional way.
Since PQ = PR [math]\Rightarrow \ \triangle[/math]PQR is an isosceles triangle. Theorem: In a triangle, sides opposite to equal angles are also equal. We know that sum of all the three angles in a triangle is [math]180^{o}[/math]. Theorem: In a triangle, the side opposite to the largest angle is the largest.
