Circles #31. If from any point on the extended common chord of 2 intersecting circles, tangents be drawn to the circles, prove that they are equal.

Re: Circles #3Hint: Through EF and FG draw perpendiculars meeting at K, now draw a circle with K as center and EF and GF tangents. 'And fun? If maths is fun, then getting a tooth extraction is fun.

Re: Circles #3No, I still do not understand how to tell that KF and KG are equal. 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Circles #3Well, can you prove this: For every pair of distinct intersecting lines, there exists at least one circle of which these lines are tangents. 'And fun?

Re: Circles #3
Because it is supposed to be an extended radii of the jumbo circle. 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Circles #3Hhmmm. Not sure this helps. Last edited by bob bundy (20140131 01:02:09) You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #13 20140131 01:44:39

Re: Circles #3I shall take a little break to let my subconscious get to work, and then come back to try that. It will be diagram number 6 so far on this problem.

Re: Circles #3
Let's try by constructing a general example of one. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #23 20140131 04:53:51
Re: Circles #3Please look at post 1 and 14. Do they look ok? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Circles #3
Hwc can you tell for sure if those lines have the same meeting point? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'
