    Help!

    Can anyone help me on how to proof this:
    If r and s are any points on a circle with center O and radius Ot, then Or is congruent to Os.
    The only thing that I can think of is using Euclid's Postulate II.
    Thank you.

    Sorry, but this is another case why other people think Math is hard.

    Because we all know that the radius of a circle is constant. So any two radii, or any 3 radii, or any razillion radii of the same circle are congruent.
    Why should Euclid's Postulate II be involved in proofing this?
