the area of a triangle

Some notes for area of triangle in circle: If the circle contain a triangle inside, we can easily calculate the area of triangle. The area of triangle is based on length of sides. We can find the area of triangle in circle is same as normal triangle area calculation.Formula for area of triangle in circle in math: For finding the area of the equilateral triangle use the simple form as A = ½ bh.The base length and height is more important for area of triangle in circle calculation. In circle, the triangle has different length of sides means we can use the heron’s formula. The perimeter is divided as half. This part is called as semi perimeter. The area of triangle in circle is = `sqrt(s (s-a) (s-b) (s-c))` . where s is represent the semi perimeter as s = `(a + b + c)/2` . If the triangle has angle size in circle means use the trigonometry formula as Area = `1/2` ab.sin c. Here two side’s length are used.
