@Hero @RadEn please help?

anonymous · Answer

i do not know the formula but there are many theorems to see if 2 chords are congruent

imstuck · Answer

Two chords that are equidistant from the center of a circle are congruent to one another; two chords that are congruent to one another are equidistant from the center.  That is what I know about chords; I'm not sure what else you  are looking for.

anonymous · Answer

same distance from the center

anonymous · Answer

they are equidistant so the chords are congruent... no equation

anonymous · Answer

yes

imstuck · Answer

There is no "way to do it".  Because it's a theorem, you don't have to worry about proving it; its already been done for you.  You have no need to prove it, only know that it's true.  To answer that question, simply state that the chords are congruent because they are an equal distance away from the center of the circle.
