comment How can I pack $45-45-90$ triangles inside an arbitrary shape ?
What Moron stopped short of saying outright is that you can lay your image on top of a square grid, then shade in all squares that are part of the shape (filled or >half filled, for small enough squares it doesn't matter), and bisect them to get the triangles you want. I don't write this as an answer because although it answers your question as written, I think it also suggests some clarifying edits you may wish to make to bring it closer to your 'real' question.

comment Is this proof of $a^{1/2}$ being either integer or irrational circular/incorrect?
Since @Bill created a meta-question, let's keep the discussion of whether to close or not there.

It's not mentioned in the question, but I guess you would like to use as few triangles as possible to accomplish this?

@Meta: In that case, would you accept Arturo's answer (or your own, if it ended up being significantly different)?

comment stopping time and martingale
@whuber: See the edit history for this question. As you can see, when @Mariano posted his comment, the title was "general question," which I agree doesn't help people figure out what is being asked.

comment Why is median age a better statistic than mean age?
Why do you say the mean should be lower than the median? While not always true, I would typically expect the mean to be higher if the distribution is positively skewed as age is.

comment Terminology for handling probabilities with partial knowledge
When you say "the person might know that 1/3 of fish are red," is this for all fish, or for the same species as "we" know about? Maybe your question could be more clear if you name the people and the fish.
