Basic Rules of Triangle . In earlier classes, we have studied that the area of a triangle whose vertices are (x1, y1), (x2, y2) and (x3, y3), is given by the expression $$\frac{1}{2} [x1(y2–y3) + x2 (y3–y1) + x3 (y1–y2)]$$. The distance of a point P(x, y) from the origin is √x 2 + y 2. SHARES. Contact us on below numbers. August 5, 2019. in 11th Class, CBSE. The law states that: a / sin A = b / sin B = c / sin C. Here were the basic that you need to know about Trigonometry Class 10. Therefore, the required area of triangular plot = 1500$\sqrt 3$ sq. Please enable Cookies and reload the page.
