For non-right angled triangles, we have the cosine rule, the sine rule and a new expression for finding area.

Read about Non-right Triangle Trigonometry (Trigonometry Reference) in our free Electronics Textbook This free triangle calculator computes the edges, angles, area, height, perimeter, median, as well as other values of a triangle. Oblique triangle calculator takes in one side length and any two other values and returns the missing values in exact value and decimal form in addition to the step-by-step calculation process for each of those missing values. According to the Law of Sines, the ratio of the measurement of one of the angles to the length of its opposite side equals the other two ratios of angle measure to opposite side. In any triangle, we can draw an altitude, a perpendicular line from one vertex to the opposite side, forming two right triangles. Right Triangle Trig Calculator Fill in two values and press Calculate. There are three possible cases: ASA, AAS, SSA. Also, the calculator will show you a step by step explanation. Using the Law of Sines to Solve Oblique Triangles. Underneath the calculator, six most popular trig functions will appear - three basic ones: sine, cosine and tangent, and their reciprocals: cosecant, secant and cotangent. Trigonometry Calculator (Sin, Cos, Tan) This trigonometry calculator is a very helpful online tool which you can use in two common situations where you require trigonometry calculations. Oblique triangles use a set of formulas unique from right triangles and these formulas can be displayed on the oblique triangle calculator page of our website. Capital letters are angles and the corresponding lower-case letters go with the side opposite the angle: side a (with length of a units) is across from angle A (with a measure of A degrees or radians), and so on. Math Warehouse's popular online triangle calculator: Enter any valid combination of sides/angles(3 sides, 2 sides and an angle or 2 angle and a 1 side) , and our calculator will do the rest! It would be preferable, however, to have methods that we can apply directly to non-right triangles without first having to create right triangles. See the non-right angled triangle given here. Additionally, if the angle is acute, the right triangle will be displayed, which can help you in understanding how the functions may be interpreted. Triangle Calculator Instructions. It will even tell you if more than 1 triangle can be created.

The number of significant values entered will determine the number of significant figures in the results. This labeling scheme is commonly used for non-right triangles. Underneath the calculator, six most popular trig functions will appear - three basic ones: sine, cosine and tangent, and their reciprocals: cosecant, secant and cotangent. You may adjust the accuracy of your results. Triangle Calculator to Solve SSS, SAS, SSA, ASA, and AAS Triangles This triangle solver will take three known triangle measurements and solve for the other three. to find missing angles and sides if you know any 3 of the sides or angles. It will even tell you if more than 1 triangle can be created. Use the calculator to find the values of the trig functions without having to perform the calculations manually. The Law of Sines can be used to solve oblique triangles, which are non-right triangles. The calculator will also solve for the area of the triangle, the perimeter, the semi-perimeter, the radius of the circumcircle and the inscribed circle, the medians, and the heights. Additionally, if the angle is acute, the right triangle will be displayed, which can help you in understanding how … Math Warehouse's popular online triangle calculator: Enter any valid combination of sides/angles(3 sides, 2 sides and an angle or 2 angle and a 1 side) , and our calculator will do the rest! Enter values three of the six sides and angles of the triangle and the other three values will be computed. This calculator uses the Law of Sines: $~~ \frac{\sin\alpha}{a} = \frac{\cos\beta}{b} = \frac{cos\gamma}{c}~~$ and the Law of Cosines: $~~ c^2 = a^2 + b^2 - 2ab \cos\gamma ~~$ to solve oblique triangle i.e. View a scaled diagram of the resulting triangle, or explore many other math calculators, as well as hundreds of other calculators addressing finance, health, fitness, and more.
