Title: Right angle triangle
Post by: Cyraxx on May 17, 2014, 02:20:59 pm

Hello!

I was wondering if there is a way to check intersection between a right angle triangle and a point or an other shape.
(or even a rectangle with 45° rotation)

Yes -- it strongly depends on the shape.

I suggest having a look at the Boost.Geometry library, it has this kind of functionality already implemented.

You should read up om basic trigonometry to help you answer those question.
