To calculate the perimeter of a triangle knowing two angles (β and γ) and the side between them (a) or an ASA triangle, we use the law of sines to find the third side and then the perimeter. We express the perimeter formula for an ASA triangle as: perimeter_ASA = a + a⋅(sin(β) + sin(γ)) / sin(β + γ)
