Match the following description with the correct theorem.

If two angles of one triangle are congruent to two angles of another triangle, then those two triangles are similar. - (a)  

In a triangle, an angle bisector divides the opposite side into segments that are proportional to the lengths of the other two sides. - (b)  

If two corresponding sides of two triangles are proportional and the included angle of those sides are congruent, then the triangles are similar. - (c)  

If the corresponding sides of two triangles are proportional, then the triangles are similar. - (d)
