Can the Isosceles Triangle Theorem be written as a biconditional? If yes, rewrite it as one, if no, explain why not.

If both a statement and its converse are true, it is a biconditional.

1. If all three angles of a triangle are equal, then all three sides are equal (equilateral).
True

2. If all three sides of a triangle are equal, then all three angles are equal.
True

Sure looks biconditional to me.
Thanks! I've been working on that problem like.. all morning.
An expression of biconditional in this case:

A triangle is equilateral if and only if all three angles are equal.

(The word "equilateral" means "equal sides".)
not sure if i’m right on this but i don’t agree necessarily with damon bc it’s isosceles triangle where only 2 angles and sides are congruent not 3. maybe he’s right and im just not understanding but that’s my take on it
