Finding angles in triangles calculator

Please provide 3 values including at least one side to the following 6 fields, and click the "Calculate" button.

Each calculation option, shown below, has sub-bullets that list the sequence of methods used in this calculator to solve for unknown angle and side values including Sum of Angles in a Triangle, Law of Sines and Law of Cosines. Specifying the three angles of a triangle does not uniquely identify one triangle. Therefore, specifying two angles of a tringle allows you to calculate the third angle only. Given the sizes of 2 angles of a triangle you can calculate the size of the third angle. Given the size of 2 angles and 1 side opposite one of the given angles, you can calculate the sizes of the remaining 1 angle and 2 sides. Given the size of 2 angles and the size of the side that is in between those 2 angles you can calculate the sizes of the remaining 1 angle and 2 sides. Given the size of 2 sides c and a and the size of the angle B that is in between those 2 sides you can calculate the sizes of the remaining 1 side and 2 angles.

Connor Smith is a professor of electrical and computer engineering with expertise in electromagnetics, microsystems, and magnetic materials and devices. Triangles are polygons with three sides and three interior angles between them. There are several types of triangles, including isosceles , equilateral , scalene, obtuse, acute, and right triangles. The Pythagorean theorem states that for a right triangle, the length of the hypotenuse squared is equal to the sum of the squares of each leg. For a right triangle with sides a and b , and a hypotenuse c , the Pythagorean theorem states:. So, if you know the length of any two sides of a right triangle, you can calculate the length of the third side using this formula. The Law of Sines or the Sine Rule states that for any oblique triangle that is, a triangle that has sides not perpendicular to each other , the ratio of a side length to the sine of its opposite angle is constant.

Pyramid volume This pyramid volume calculator helps in finding the volume of a pyramid with a regular base or with a known base area. Depending on what is given, you can use different relationships or laws to find the missing side:.

Triangle angle calculator is a safe bet if you want to know how to find the angle of a triangle. Whether you have three sides of a triangle given, two sides and an angle or just two angles, this tool is a solution to your geometry problems. Below you'll also find the explanation of fundamental laws concerning triangle angles: triangle angle sum theorem, triangle exterior angle theorem, and angle bisector theorem. Read on to understand how the calculator works, and give it a go - finding missing angles in triangles has never been easier! If the angle is between the given sides, you can directly use the law of cosines to find the unknown third side, and then use the formulas above to find the missing angles, e. If the angle isn't between the given sides, you can use the law of sines.

This angle of a right triangle calculator will help you determine what the angles of a right triangle are - that is, if you know the measurements of at least two of its sides or at least one of its sides together with its area. Keep on reading to learn about:. In equation form, we express that as:. On the other hand, if we do not know any of the two angles, we can still find them with the help of some basic trigonometric functions. With those equations, we can see that if we have the measurements of at least two sides of our right triangle, we can determine what the angles of a right triangle are. What if you only know the measurement of one leg? For that, you should at least also know the area of your right triangle to derive the other side of your triangle using one of these equations:. Then you can use the formulas we previously discussed to find the missing angles of your right triangle. The fun part is that we have already utilized these equations in this calculator for your convenience.

Please provide 3 values including at least one side to the following 6 fields, and click the "Calculate" button. A triangle is a polygon that has three vertices. A vertex is a point where two or more curves, lines, or edges meet; in the case of a triangle, the three vertices are joined by three line segments called edges. A triangle is usually referred to by its vertices. Furthermore, triangles tend to be described based on the length of their sides, as well as their internal angles. For example, a triangle in which all three sides have equal lengths is called an equilateral triangle while a triangle in which two sides have equal lengths is called isosceles. When none of the sides of a triangle have equal lengths, it is referred to as scalene, as depicted below.
