Geometry Inscribed Triangle

Click For Summary

The discussion revolves around finding the side lengths of a triangle inscribed in a circle with a radius of 3, given angles A and B. Participants express confusion over the relevance of arc lengths and the application of the Law of Sines, specifically the ratio a/sin(A) = b/sin(B) = c/sin(C) = 2R. There is debate about the correctness of using the Law of Cosines versus the Law of Sines, with some participants asserting that the latter is more straightforward for this problem. Ultimately, the conversation highlights the importance of understanding fundamental trigonometric relationships in solving geometry problems involving inscribed triangles.

You should know it or know how to demonstrate it, but maddie did you explain from where you got the 3, not for me but in the papercheet to give to the teacher, maths should be logic and precise, in fact using sine here is a stright direct application of it not turning around loop and using cos,

I couldn't possibly know something I hadn't previously heard of. The fact that the radius is 3 was given in the task. This isn't something I'm handing in, I'm preparing for an exam, so no one but myself sees it :-) That doesn't make it wrong though, haha.
