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.
SAS theorem states that two triangles are equal if two sides and the angle between those two sides are equal. While the geometry formula for the area of a triangle is often used, the SAS theorem is used with trigonometry to provide an alternate method to calculate the area of a triangle.
