Trigonometry is a branch of mathematics that gives the relationships between side lengths and angles of triangles. All trigonometric angles have fixed values and they can also be defined by the ratio of the lengths of the sides in a right-angled triangle. The six trigonometric as mentioned above are Sine, cosine, tangent, cotangent, cosecant, and secant. For a right-angled triangle, there is two way to obtain the relationship among all the sides of the triangle. The trigonometric ratios provide the ratio of two of the sides of the triangle, and the Pythagoras theorem provides the relationship among all the sides. Below is the table providing the ratios,. The Pythagoras theorem says that the square of the hypotenuse biggest side of the right-angled triangle is equal to the sum of the squares of the rest of the sides base and perpendicular.

In Triangle ABC with the right angle at C , let a , b , and c be the opposite, the adjacent, and the hypotenuse of angle A. Then, we have. Let the other two angles be x and y which will be acute. Right triangles are a special case of triangles. You always know at least one angle, the right angle, and depending on what else you know, you can solve the rest of the triangle with fairly simple formulas. If you know any one side and one angle, or any two sides, you can use the pneumonic soh-cah-toa to remember which trig function to use to solve for others. Opposite refers to the side which is not part of the angle, adjacent refers to the side that is part of the angle, and the hypotenuse is the side opposite the right angle, which is C in the image above. For example,lets say you know the length of a and the value of angle A in the above triangle. Using the cosine function you can solve for c , the hypotenuse. If you know the length of both sides a and b , you can solve for the tangent of either angle A or B.

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:.
