I'm in the midst of writing a module in Common Lisp 1 and I need to calculate the distance of a hypothetical line projected perpendicularly from apex of the right angle of (various) triangles to the opposite side.
I'm not the greatest at trig; I can calculate for a given triangle but I don't know the formula to actually bisect a triangle.
In the attached illustration, the distance I am trying to calculate is indicated by the green arrow. (L)
Information that I have:
1) Lengths of sides A, B and C
2) There will always be at least 1 right angle.
Information I can gather if necessary:
a) The two non-right angles.
b) The perimeter
II don't necessarily need any help with the actual code (Unless there's a Lisp function I'm unfamiliar with). What I'm after is the the generic geometric formula that will lead me to the information I'm after.
Any advice for me?
Thanks in advance
