Angle calculator right angle triangle

Right Angle Calculator is a free online tool that displays the angle measure, area and the unknown side of the right triangle.

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.

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. To use our angle of a right triangle calculator, all you have to do is enter any two known sides of your right triangle.

Missing side and angles appear.

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:.

Similar notation exists for the internal angles of a triangle, denoted by differing numbers of concentric arcs located at the triangle's vertices. 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. If you want to expand your knowledge about triangles even further, here is a list of our other triangle calculators that you can check out:. It is the edge opposite to the right angle and is c in this case. Watch Now. What are the 3 angles of a right triangle? To find the angles of this right triangle:. 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. To solve a triangle with one side, you also need one of the non-right angled angles. To find the angles of a right triangle we use trigonometry. What if you only know the measurement of one leg? Now we know that:. At least one dimension, of edge-length or area, has to be supplied. 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.

Otherwise, the triangle will have no lines of symmetry. Reset defaults. In mathematics, a triangle is a two-dimensional figure with three sides. Are all right triangles similar? It is worth noting that all triangles have a circumcircle circle that passes through each vertex , and therefore a circumradius. 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:. Standard Deviation Calculator.
