----
sin(theta) = (side opposite theta)/(hypotenuse)
-----
cos(theta) = (side adjacent to theta) / hypotenuse
-------
tan(theta) = (side opposite theta)/(side adjacent to theta)

Let ABC be right triangle with angle C as right angle.
BC is the base of the triangle.
AB is perpendicular to BC
Sine angle C =AB/AC
Sine angle A = BC/AC
angle B = 90deg
