Conditional Statement: If a triangle has 3 congruent sides, then it's an equilateral triangle.

Identify the converse of this conditional statement:

• If a triangle does not have 3 congruent sides, then it's not an equilateral triangle.

• If a triangle is equilateral, then it has 3 congruent sides.

• If a triangle is not equilateral, then it does not have 3 congruent sides.

• If a triangle has 3 congruent sides, then it's not an equilateral triangle.

Conditional Statement: If a triangle has 3 congruent sides, then it's an equilateral triangle.

Identify the inverse of this conditional statement:

• If a triangle does not have 3 congruent sides, then it's not an equilateral triangle.

• If a triangle is equilateral, then it has 3 congruent sides.

• If a triangle is not equilateral, then it does not have 3 congruent sides.

• If a triangle has 3 congruent sides, then it's not an equilateral triangle.
