This calculator calculates for the length of one side of a right triangle given the length of the other two sides. A right triangle has two sides perpendicular to each other. Sides "a" and "b" are the perpendicular sides and side "c" is the hypothenuse. Enter the length of any two sides and leave the side to be calculated blank.


This calculator will use the Pythagorean Theorem to solve for the missing length of a right triangle given the lengths of the other two sides. Plus, unlike other online calculators, this calculator will show its work and draw the shape of the right triangle based on the results.


This Pythagorean theorem calculator will calculate the length of any of the missing sides of a right triangle, provided you know the lengths of its other two sides. This includes calculating the hypotenuse. The hypotenuse of the right triangle is the side opposite the right angle, and is the longest side.


Calculator online for an parallelogram. Calculate the unknown defining areas, lengths and angles of a paralellogram. Online calculators and formulas for an annulus and other geometry problems.


Law of sines: the ratio of the length of a side of a triangle to the sine of its opposite angle is constant. Using the law of sines makes it possible to find unknown angles and sides of a triangle given enough information. Where sides a, b, c, and angles A, B, C are as depicted in the above calculator, the law of sines can be written as shown ...
