Hello ychst and welcome to MHB! :D

We ask that our users show their progress (work thus far or thoughts on how to begin) when posting questions. This way our helpers can see where you are stuck or may be going astray and will be able to post the best help possible without potentially making a suggestion which you have already tried, which would waste your time and that of the helper.

Can you post what you have done so far?

Also, please do not post duplicates of the same problem. :)

Re: Geometry challenge problem

Hi Greg, thank you for your reply. Apologies for posting in different forums. I initially thought it would be seen be people with different interest/expertise. Below is my attempt at solving the problem. I am trying to validate whether my answer is correct. Thank you. View attachment 6542

Re: Geometry challenge problem

That's correct. Good work. I suppose the challenge now is to find a solution that only uses geometry. :)

Re: Geometry challenge problem

Exactly, that's what I'm kind of stuck on. Does anyone have a pure geometry solution?

Does anyone have a pure geometry answer to this question?

Re: Geometry challenge problem

Hello ychst,

MHB rule #1 states:

No bumping. Bumping a thread is posting a reply to that thread solely to raise its profile and return it to the top of the active threads list. This is forbidden at MHB. If you want to draw attention to an unanswered thread, then post something of value such as further progress. It is also forbidden to bump one thread by drawing attention to it in a different thread.

This rule is designed to make MHB more useful and efficient for everyone. When you bump a thread this adds no content and yet draws attention to it, causing people to possibly take time to see what has been added only to find that no content has actually been added. This can waste the time of our helpers, and this time is very valuable. Any time we can save on the part of the volunteer helpers would, I hope you can see, help you in the long run! So, if you could please help us help you in this way, by not bumping, we would greatly appreciate it.

We ask that you be patient and wait for someone to reply. You are of course welcome to post your progress or additional thoughts that have occurred in the meantime.

We ask that you keep this policy in mind in the future. We also ask that you consider how much less efficient MHB would be if this posting behavior was allowed.
