10.1 Non-right Triangles: Law of Sines - OpenStax
WEBIn any triangle, we can draw an altitude, a perpendicular line from one vertex to the opposite side, forming two right triangles. It would be preferable, however, to have methods that we can apply directly to non-right triangles without first having to create right triangles.

WEBGiven an arbitrary non-right triangle, we can drop an altitude, which we temporarily label h, to create two right triangles. Using the right triangle relationships, b h sin(α) = and a h sin(β) = . Solving both equations for h, we get bsin( α) = h and asin( β) = h. Since the h is the same in both equations, we establish bsin( α) = asin(β ...
