*Isosceles triangles* are those that have two sides equal in length.

*Equilateral triangles* are those that have all three sides equal.

These are not the same.

#### Explanation:

Any equilateral triangle (it has all 3 equal sides) is isosceles (that requires only 2 equal sides), but not all isosceles triangles (it has 2 equal sides) are equilateral (that requires all 3 equal sides).
