The video tutorial explains the derivation of the triangle area formula 1/2 ab sin C. It begins by introducing the formula and describing the triangle's components, including vertices and sides. The derivation process involves using the basic area formula 1/2 base times height and applying trigonometric principles, specifically SOHCAHTOA, to express the height in terms of the sine of angle C. The final step involves substituting this expression into the area formula to arrive at the desired formula.
