Question

which venn diagram accurately represents the information in the following statement? \if a triangle is equilateral then it is isosceles.\

Explanation:

Step1: Understand the relationship

An equilateral triangle has all three sides equal. An isosceles triangle has at least two sides equal. So every equilateral triangle is an isosceles triangle, but not every isosceles triangle is equilateral. This means the set of equilateral triangles is a subset of the set of isosceles triangles.

Answer:

The first Venn - diagram (where "Equilateral" is a circle inside the "Isosceles" circle, and "Isosceles" is inside the "Triangles" rectangle) is the correct one.
