Step 2:
: Understand the definitions

- An isosceles triangle is a triangle with at least two equal sides - An equilateral triangle is a triangle with all three sides equal in length

Step 3:
: Analyze the relationship between isosceles and equilateral triangles

- Every equilateral triangle is automatically an isosceles triangle (since all sides are equal) - Not every isosceles triangle is equilateral (some have only two equal sides)
