Question

To prove: "The perpendicular from centre of a circle to the chord, bisects the chord." The proof started from assumption "Let OM be the perpendicular to chord AB".

This method of proof is

• A. The proof by contradiction
• B. The Direct method.
• C. Induction method.
• D. The proof by contrapositive method.

Answer 1

The correct option is B The Direct method.

In direct method we have to assume the hypothesis as we have assumed the hypothesis "Let OM be the perpendicular to chord AB" in this case hence the option is $B$
