Equilateral/Equianglar

                 

                                                                                                                                                                                                                                                                                                                                                                          A triangle which has all three interior angles equal (congruent).

 

The sides of an equiangular triangle are all the same length (congruent), and so an equiangular triangle is really the same thing as an equilateral triangle. See Equilateral Triangles.
