Answer 1

Answer:

The chord of a circle which are equidistant from the centre are equal chords of a circle are equidistant

Answer 2

Theorem: Equal chords of a circle are equidistant from its center. Proof: Compare ΔOAX Δ OX with ΔOCY Δ O C Y .By the RHS criterionΔOAX≡ΔOCY Δ O A X ≡ Δ O C Y .Thus, OX = OY, which means that AB and CD are equidistant from O.
