Will someone tell me about this circle and chord relation?In the adjoining figure, 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #2 20120523 23:25:48
Re: Will someone tell me about this circle and chord relation?First fin BAD from the triangle ABD,and get BCD from the fact that the quadrilayeral ABCD is inscribed in a circle,which means that BAD+BCD=180°. The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #3 20120523 23:35:19
Re: Will someone tell me about this circle and chord relation?How do you know that BAD+BCD=180 degrees? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun.

Re: Will someone tell me about this circle and chord relation?Isn't (3) just a special case of (1)?
