**Using Sine to Calculate the Area of a Triangle Math**

Concept Using the standard formula for the area of a triangle, we can derive a formula for using sine to calculate the area of a triangle.... We can find the area of triangle using the formula A = $\frac{1}{2}$ base x height. The area formula using Trigonometry helps avoid finding the height of the triangle.

**Example Determine the Area of a Triangle Using the Sine**

Concept Using the standard formula for the area of a triangle, we can derive a formula for using sine to calculate the area of a triangle.... Note: You can use sine to help you find the area of a triangle! All you need is two sides and an angle measurement! This tutorial helps you find this formula.

**Example Determine the Area of a Triangle Using the Sine**

In this tutorial the instructor shows how to find the area of an oblique triangle using different formulas. To find the area of an oblique triangle there are different formulae. The first formula to calculate the area of a triangle is area A = (1/2) * a * b * Sin(C), where a and b are the lengths of the two sides of the triangle and C is the... Concept Using the standard formula for the area of a triangle, we can derive a formula for using sine to calculate the area of a triangle.

## How To Find Area Of Triangle Using Sine

### Using the sine rule, c/sinC = 2R where R is the circumradius of the triangle. This gives Â½absinC = Â½ab(c/2R) = abc/4R. The circumradius the radius of the circumcirle, and the circumcircle is the circle which passes through the theee vertices of ABC. To construct the circumcirle you must find the intersection of the perpendicular bisector of the three sides, which meet at the circumcentre.

- The sine of an angle theta that is part of a right triangle, not the right angle, is the opposite side divided by the hypotenuse. As a result, you could determine the hypotenuse by dividing the opposite side by the sine â€¦
