To calculate the area of a triangle given one side and two angles, solve for another side using the Law of Sines, then find the area with the formula: area = 1/2 × _b_ × _c_ × sin(A). Find Third Angle Determine the third angle of the triangle. For example, ...
Input the lengths of triangle sides you know. For instance, if you are asked to find the length of a hypotenuse (the longest side of the right triangle) of a triangle where one side (a) equals 2 and another side (b) equals 5, you can find the length of the hypotenuse with the fol...
Just like every other triangle, a right triangle has three sides. One of them is the hypothenuse, which is the side opposite to the right angle. The other two sides are identified using one of the other two angles. The other angles are formed by the hypothenuse and one other side. T...
Calculating the sides of a triangle helps you to determine the perimeter of a triangle even if you only have the measure of two of the angles and one of the sides. To find the sides of the triangle, you need to use the Law of Sines. A scientific calculator with trigonometric functions ...
It can help you find the length of a side of a right triangle as long as you have an angleθ\thetaθand some info on the other sides of the triangle. Example problems In this chapter, we're actually going to focus on the cosine rule. This means we'll only be working with the "...
TheLaw of Cosinesconnects a triangle’s side lengths and angles, making it important for solving non-right triangles where thePythagorean theoremcannot be used. Stated asc² = a² + b² – 2ab * cos(θ)for a triangle with sidesa,b, andcand angleθopposite side c, the Law of Cosi...
For example, let’s calculate the secant of angle α in a triangle with the length of the hypotenuse equal to 8 and the adjacent side equal to 6. sec(α) = 8 / 6 = 4 / 3 Secant vs. Arccos Secant should not be confused with arccos, which is the inverse of the cosine function...

Properties of a Right TriangleIn geometry, a right triangle is a specific triangle that has one of its interior angles exactly at the right angle. Its longest side is known as the hypotenuse, the side just opposite to an acute angle is called the opposite...
