Angle calculator for triangle

The calculator will try to find all sides and angles of the triangle right triangle, obtuse, acute, isosceles, equilateralas well as its perimeter and area, with steps shown.

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.

Angle calculator for triangle

Finding the missing side or angle couldn't be easier than with our great tool — right triangle side and angle calculator. Choose two given values, type them into the calculator, and the calculator will determine the remaining unknowns in a blink of an eye! If you are wondering how to find the missing side of a right triangle, keep scrolling, and you'll find the formulas behind our calculator. There are a few methods of obtaining right triangle side lengths. Depending on what is given, you can use different relationships or laws to find the missing side:. If you know two other sides of the right triangle, it's the easiest option; all you need to do is apply the Pythagorean theorem:. If leg a is the missing side, then transform the equation to the form where a is on one side and take a square root:. As we remember from basic triangle area formula , we can calculate the area by multiplying the triangle height and base and dividing the result by two. A right triangle is a special case of a scalene triangle, in which one leg is the height when the second leg is the base, so the equation gets simplified to:. For example, if we know only the right triangle area and the length of the leg a , we can derive the equation for the other sides:.

It is the edge opposite to the right angle and is c in this case. How to find the missing side of a right triangle? Embed Share via.

Please provide 2 values below to calculate the other values of a right triangle. Right triangles, and the relationships between their sides and angles, are the basis of trigonometry. The sides of a right triangle are commonly referred to with the variables a, b, and c, where c is the hypotenuse and a and b are the lengths of the shorter sides. The altitude divides the original triangle into two smaller, similar triangles that are also similar to the original triangle. If all three sides of a right triangle have lengths that are integers, it is known as a Pythagorean triangle. In a triangle of this type, the lengths of the three sides are collectively known as a Pythagorean triple.
