| A | B |
| If 2 sides of a triangle are congruent | Then the base angles are congruent |
| If 2 angles of a triangle are congruent | Then the sides opposite those angles are congruent. |
| If a point lies on the perp. bisector of a seg. | Then the point is equidistant from endpts of the segment |
| If a point is equidistant from the endpts. of a segment | Then the point lies on the perp. bisector of the segment |
| If a point lies on the bisector of an angle | Then the point is equidistant from the sides of the angle |
| If a point is equidistant from the sides of an angle | Then the point lies on the bisector of the angle |
| If a triangle is equilateral | Then it is also equiangular |
| If a triangle is equiangular | Then it has three 60 angles |
