Right Triangle ShapeA = angle A a = side a B = angle B b = side b C = angle C c = side c Show
K = area See Diagram Below: *Length units are for your reference only since the value of the resulting lengths will always be the same no matter what the units are. Calculator UseA right triangle is a special case of a triangle where 1 angle is equal to 90 degrees. In the case of a right triangle a2 + b2 = c2. This formula is known as the Pythagorean Theorem. In our calculations for a right triangle we only consider 2 known sides to calculate the other 7 unknowns. For example, if we know a and b we can calculate c using the Pythagorean Theorem. c = √(a2 + b2). Once we know sides a, b, and c we can calculate the perimeter = P, the semiperimeter = s, the area = K, and the altitudes: ha, hb, and hc. Let us know if you have any other suggestions! Formulas and Calculations for a right triangle:
1. Given sides a and b find side c and the perimeter, semiperimeter, area and altitudes
2. Given sides a and c find side b and the perimeter, semiperimeter, area and altitudes
For more information on right triangles see: Weisstein, Eric W. "Right Triangle." From MathWorld--A Wolfram Web Resource. Right Triangle. Weisstein, Eric W. "Altitude." From MathWorld--A Wolfram Web Resource. Altitude. Additional Information Note that giving the sizes of the two angles, A & B will not allow any
other sizes to be found. At least one dimension, of edge-length or area, has to be supplied. Our online tools will provide quick answers to your calculation and conversion needs. On this page, you can solve math problems involving right triangles. You can calculate angle, side (adjacent, opposite, hypotenuse) and area of any right-angled triangle and use it in real world to find height and distances.

Right triangle calculationFormulas used for calculations on this page: Pythagoras' Theorem Trigonometric functions: Area = a*b/2, where a is height and b is base of the right triangle. © everydaycalculation.com What is the formula for a right triangular?In a right triangle with cathetus a and b and with hypotenuse c , Pythagoras' theorem states that: a² + b² = c² . To solve for c , take the square root of both sides to get c = √(b²+a²) . This extension of the Pythagorean theorem can be considered as a "hypotenuse formula".
