Right triangle calculatorPlease enter two properties of the right triangle Triangle: Use symbols: a, b, c, A, B, h, T, p, r, R To calculate the properties of a right triangle when given certain information, you can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. The theorem can be written as: c2 = a2 + b2 where c is the length of the hypotenuse, and a and b are the lengths of the other two sides. If you know the length of the hypotenuse and one of the other two sides, you can use the Pythagorean theorem to find the length of the remaining side. For example, if you know the length of the hypotenuse is c and the length of one of the legs is a, you can find the length of the other leg by: b2 = c2 - a2 Additionally, you can use the Pythagorean theorem to find the measure of the angles in a right triangle. You can use the inverse trigonometric functions such as arctan, arcsin, arccos to find the angles. If you know the side lengths, you can use the trigonometric functions to find the angles: sin α = a/c cos α = b/c tan α = a/b It's important to note that the Pythagorean theorem holds true only for right triangles. If the triangle is not a right triangle, this theorem will not work.The right triangle calculator computes angles, sides (adjacent, opposite, hypotenuse), and area of any right-angled triangle for real-world applications. Two independent properties entirely determine any right-angled triangle. The calculator provides a step-by-step explanation for each calculation. A right triangle is a type of triangle that has one angle measuring C=90°. In a right triangle, the side c that is opposite the C=90° angle is the longest side of the triangle and is called the hypotenuse. The symbols a and b are the lengths of the shorter sides, also called legs or catheti. Symbols for angles are A (or α alpha) and B (or β beta). Symbol h refers to the altitude (height) of the triangle, which is the length of the perpendicular line segment drawn from the vertex C to the hypotenuse.
