Side-angle-side similarity theorem
|
If the angle one triangle is congruent to an angle of a second triangle and the lengths of the sides including the angles are proportional, then the triangles are similar.

|
Triangle proportionality theorem
|
If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally.

|
Converse of the triangle proportionality theorem
|
If a line divides two sides of a triangle proportionally, then it is parallel to the third side.
