Online triangle calculator

The triangle calculator finds all triangle measurements — side lengths, triangle angles, area, perimeter, semiperimeter, heights, medians, inradius, and circumradius. The triangle calculator is an online online triangle calculator solver allowing you to find all triangle measurements based on three known measurements quickly.

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:.

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. Examples include: 3, 4, 5; 5, 12, 13; 8, 15, 17, etc. Area and perimeter of a right triangle are calculated in the same way as any other triangle. The perimeter is the sum of the three sides of the triangle and the area can be determined using the following equation:. 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.

This is the obtuse triangle in Quadrant II, for more information on this topic, check out the law of sines ambiguous case.

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.

Enter any valid input 3 side lengths, 2 sides and an angle or 2 angle and a 1 side and our calculator will do the rest. This is the acute triangle in Quadrant I, for more information on this topic, check out the law of sines ambiguous case. This is the obtuse triangle in Quadrant II, for more information on this topic, check out the law of sines ambiguous case. Status: Calculator waiting for input. The most frequent reason for this is because you are rounding the sides and angles which can, at times, lead to results that seem inaccurate. In these cases, in actuality , the calculator is really producing correct results.

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.

How to find the angle? The inradius is the radius of the largest circle that will fit inside the given polygon, in this case, a triangle. Examples include: 3, 4, 5; 5, 12, 13; 8, 15, 17, etc. For the purposes of this calculator, the inradius is calculated using the area Area and semiperimeter s of the triangle along with the following formulas:. Foci of an Ellipse Calculator. The circumcenter of the triangle does not necessarily have to be within the triangle. Refresh the calculator. No, a right triangle cannot have all 3 sides equal , as all three angles cannot also be equal. In these cases, in actuality , the calculator is really producing correct results. Side B.
