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. Given the sizes of the 3 sides you can calculate the sizes of all 3 angles in the triangle. You could also use the Sum of Angles Rule to find the final angle once you know 2 of them. If a, b and c are the lengths of the legs of a triangle opposite to the angles A, B and C respectively; then the law of sines states:.

The medians of the triangle are represented by the line segments m am band m c. If you know one angle apart from the right angle, the calculation of the third one is a piece of cake:. Embed Share via.

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.

A triangle is a three-sided polygon. The sum of the angles of a triangle is always degrees. Each angle in a triangle is called a vertex angle, and there are three vertex angles in every triangle. Knowing the measures of the vertex angles of a triangle can help you solve many mathematical problems involving triangles. For example, if two of the vertex angles in a triangle are 40 degrees and 60 degrees, the formula would be:. Also triangle angles can be found by knowing all three sides of the triangle through the cosine theorem. The formula is:. Our triangle angles calculator makes it easy for you to find the measures of the vertex angles in your triangle. Simply enter the lengths of the three sides, and the calculator will automatically calculate the measure of the three angles. This tool is perfect for students, teachers, and anyone else who needs to calculate triangle angles quickly and accurately.

If you want to measure angles, but you don't have a protractor at hand, you can take measurements using this online angle meter. You don't need to install any protractor applications on your smartphone or computer because this online tool simply works in a browser. Being launched on a smartphone or tablet, the application uses the capabilities of the built-in accelerometer to determine the tilt of the device. So you can just rotate the mobile phone to measure the angle of inclination. To use it similarly to a native mobile app, you can add a shortcut via the menu item "Add to Home Screen" or "Add to Phone" in the browser. Without a phone, you can still use the protractor online, setting the angles manually with mouse clicks, scrolling the mouse wheel, or simply entering the angle in the text input.

To solve a triangle with one side, you also need one of the non-right angled angles. If all three sides of a right triangle have lengths that are integers, it is known as a Pythagorean triangle. Given two triangle sides and one angle 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. Thus, in this type of triangle, if the length of one side and the side's corresponding angle is known, the length of the other sides can be determined using the above ratio. Depending on what is given, you can use different relationships or laws to find the missing side:. Basic Calculator. The medians of the triangle are represented by the line segments m a , m b , and m c. In a triangle of this type, the lengths of the three sides are collectively known as a Pythagorean triple. Type in the given values. But hey, these are three interior angles in a triangle! Reviewed by Bogna Szyk and Jack Bowater. Tick marks on the edge of a triangle are a common notation that reflects the length of the side, where the same number of ticks means equal length. They are similar if all their angles are the same length, or if the ratio of two of their sides is the same.

FAQ How do I find angles in a triangle? Plant spacing Optimize your garden layout with our garden spacing calculator. Likely the most commonly known equation for calculating the area of a triangle involves its base, b , and height, h. Now we know that:. Reviewed by Connor Smith, PhD. Find out which formulas you need to use. Embed Share via. Therefore, specifying two angles of a tringle allows you to calculate the third angle only. Unlike the previous equations, Heron's formula does not require an arbitrary choice of a side as a base, or a vertex as an origin. An angle bisector of a triangle angle divides the opposite side into two segments that are proportional to the other two triangle sides.
