Equilateral --> 3 equal sides Isosceles --> 2 equal sides only Scalene --> 3 unique sides

a biconditional"All triangles have 3 sides" and "A polygon with 3 sides is a triangle" can be combined as "A polygon is a triangle if and only if it has 3 sides."The phrase "if and only if" is often abbreviated as "iff".
