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.
The law of sines is based on the proportionality of sides and angles in triangles. The law states that for the angles of a non-right triangle, each angle of the triangle has the same ratio of angle measure to sine value. If you are given the lengths of two sides and the measure of an angle opposite one of those sides, you can use the law of sines to find the other opposite angle. The measure of the third angle can be easily found using the fact that the sum of the angles of a triangle is 180Âº.
