Re: altituds

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

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
