Capital-letter variable names correspond to angle measures, opposite from each side length named by the lowercase-letter counterpart. All angle measure inputs are in degrees (pre-multiplied by 180:pi). The side lengths a, b and c are in arbitrary units and do not at all affect the triangle size or drawing in any way, other than to help compute any unknown angle measures.
|Quadrant II (90 to 180 degrees)||Quadrant I (0 to 90 degrees)|
I also maintain a separate research project to derive many exact trigonometric ratios so that many of these answers can be expressed in exact form.
