The best description of the RAR rule is:
Select one:
a. If the angle of one triangle is the same as the angle of another triangle and the sides containing these angles are in the same ratio, then the triangles are similar.
b. If the angle of one triangle is the same as the angle of another triangle and one side containing the angle are in the same ratio, then the triangles are similar.
c. If the angle of one triangle is the same as the angle of another triangle and one side containing the angle are in the same plane, then the triangles are similar.
d. If the angle of one triangle is greater than the angle of another triangle and the sides containing these angles are in the same ratio, then the triangles are similar
