Right angled triangle length calculator

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

Show values to. Additional Information The usual way of identifying a triangle is by first putting a capital letter on each vertex or corner. Like, for example, A B C. Now, a reference to A can mean either that vertex or, the size of the angle at that vertex. Here it means the size. The edges are identified by using the small version of the opposite vertex-letter.

The right triangle calculator will help you find the lengths of the sides of a right-angled triangle. This triangle solver will also teach you how to find the area of a right triangle as well as give plenty of information about the practical uses of a right triangle. First things first, let's explain what a right triangle is. In a right-angled triangle, we define the sides in a special way. The side opposing the right angle is always the biggest in the triangle and receives the name of "hypotenuse". The other two sides are called catheti. The relationship between the hypotenuse and each cathetus is straightforward, as we will see when we talk about Pythagoras' theorem. If all you want to calculate is the hypotenuse of a right triangle, this page and its right triangle calculator will work just fine. However, we would also recommend using the dedicated tool we have developed at Omni Calculators: the hypotenuse calculator. The hypotenuse is opposite the right angle and can be solved by using the Pythagorean theorem. We can consider this extension of the Pythagorean theorem as a "hypotenuse formula". A Pythagorean theorem calculator is also an excellent tool for calculating the hypotenuse. Let's now solve a practical example of what it would take to calculate the hypotenuse of a right triangle without using any calculators available at Omni:.

The so-called "45 45 90" triangle is probably the most special among all the special right triangles. Sometimes two different solutions are possible.

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:.

The triangle length calculator tells you the length of the third side if you enter two sides and an angle. A triangle has three sides and three angles. To this end, you need to employ a sine law or the cosine law to relate them to each other. Sine or cosine forms the crux of trigonometry functions that have numerous applications. One is about finding the third side or any angle for a triangle: the calculator and the accompanying text do the same. Read on to understand more about triangle length and cosine law. The sides of the triangle are related to each other with the cosine law :.

Still, with a bit of skill, you can use the same idea and calculate the area of a parallelogram using right-angled triangles. To find the angles of a right triangle we use trigonometry. Then using right-angled triangles and trigonometry, he was able to determine the angle going from the center of the Earth between the well and the pole, as well as the radius of the Earth , based on the known distance between these two points. The sides of a triangle have a certain gradient or slope. Both its catheti are of the same length isosceles , and it also has the peculiarity that the non-right angles are exactly half the size of the right angle that gives the name to the right triangle. Do 2, 3, and 4 make a right triangle? The so-called "45 45 90" triangle is probably the most special among all the special right triangles. Let's now solve a practical example of what it would take to calculate the hypotenuse of a right triangle without using any calculators available at Omni:. The consequences of this can be seen and understood with the 30 60 90 triangle calculator , but for those who are too lazy to click the link, we will summarize some of them here. How do you solve a right angle triangle with only one side? To find the perimeter, or distance around, our triangle we simply need to add all three sides together.

Finding the missing side or angle couldn't be easier than with our great tool — right triangle side and angle calculator.

How to find the area of a right triangle We have already seen that calculating the area of a right angle triangle is very easy with the right triangle calculator. This is precisely what we already saw by just cutting the rectangle by the diagonal. Aside from the right-angled triangle, there are other special triangles with interesting properties. That is, 2, 3, and 4 do not form a Pythagorean triple; in other words, there is no right triangle with sides 2, 3, and 4. Example Let's show how to find the sides of a right triangle with this tool: Assume we want to find the missing side given area and one side. Now we're gonna see other things that can be calculated from a right triangle using some of the tools available at Omni. We just need to find one special button on our handheld calculators. Otherwise, the triangle will have no lines of symmetry. Depending on what is given, you can use different relationships or laws to find the missing side:. Pythagorean triplets, triangles meet maths Geometry and polygons, especially triangles, always come together. Let's see how. The circumradius is defined as the radius of a circle that passes through all the vertices of a polygon, in this case, a triangle. Here it means the size. The center of this circle, where all the perpendicular bisectors of each side of the triangle meet, is the circumcenter of the triangle, and is the point from which the circumradius is measured. However, we would also recommend using the dedicated tool we have developed at Omni Calculators: the hypotenuse calculator.
