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. Please check out also the Regular Triangle Calculator and the Irregular Triangle Calculator.

From the Pythagorean Theorem: c²=a² + b²
Calculate for side c		Calculate for side a		Calculate for side b
c²=a² + b²		c²=a² + b²		c²=a² + b²
c=√a² + b²		a²=c² - b²		b²=c² - a²
		a=√c² - b²		b=√c² - a²
