Re: altituds

I am looking at it now. If you change AB the distance varies.


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?

Re: altituds

In my diagram and if Y is the point on AC where XY is perpendicular to AC then

AYX and AMX are congruent (SAA) so the size of AB is irrelevant.

Re: altituds

It does. But it stays the same as MX.

Re: altituds

MX changes too because it is a perpendicular bisector of AB. If AB lengthens MX will change too.

Re: altituds

Here's my diagram.

MX is given as 9, so it cannot change.

Re: altituds

Hi bobbym

I do not think you understand me. The distance from X to AC is always the same as MX. Bob has a nice proof up there.

Re: altituds

I am sorry, your comment in post #21 confused me. I already solved this in post#20. I thought you had found something wrong with that answer, and got mixed up.

Re: altituds

No, no. I just stated that we do not need the length of AB.

Re: altituds

Because of the fact that Flux does not tell you when a post has been put just prior to yours, I was posting for your posts and did not see any of his!

My apologies to Bob.

Re: altituds

No apology necessary.  I'm happy to have been able to provide a quick solution.  For once my pencil and paper worked more quickly than my software.  smile
