Write an "if...then" statement that can be written from the given statement: "A triangle is an equilateral triangle if and only if the triangle has three congruent sides."

Select the correct converse of the conditional statement written using the statement from the previous question: A triangle is an equilateral triangle if and only if the triangle has three congruent sides.

• If the triangle is equilateral then it has three congruent sides.

• If the triangle has three congruent sides then it is equilateral.

• A triangle is equilateral only when it has three congruent sides.

• Both statements are equivalent.
