| If an angle of one triangle is congruent to an angle of another triangle and the sides including those angles are in proportion, then the triangles are similar | |
| If 2 angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. | |
| ad=bc | |
| If three parallel lines intersect two transversals, then they divide the transversals proportionally. | |
| If a ray bisects an angle of a triangle, then it divides the opposite side into segments proportional to the other two sides. | |
| a/b = c/d = e/f = ..., then (a+c+e+...)/(b+d+f+...) = a/b) | |
| If the sides of two triangles are in proportion, then the trianlges are similar. | |
| If a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally. | |
| (a+b) / b = (c+d) / d | |
