Can you use Pythagorean Theorem if only one side length is given?
You can only use the pythagorean theorem if the one angle you know is a right angle. If it is not a right angle you must use either law of cosines or law of sines. If the known angle is formed by the two know sides use the law of cosines.
How do you find two missing sides?
Given two sides
- if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² – b²)
- if leg b is unknown, then. b = √(c² – a²)
- for hypotenuse c missing, the formula is. c = √(a² + b²)

How do you check if a triangle is a right triangle?
Finally, the Learn tab also includes a mini calculator that checks to see if the given lengths of three sides of a triangle form a right triangle (Converse of Pythagorean Theorem). If you are unfamiliar with the Pythagorean Theorem, it may help to visit the Learn tab before using the calculator.
What is the formula to find the area of a triangle?
This is the area of the right triangle formed by Leg a, Leg b, and Leg c (hypotenuse). The formula used is, Area (K) = 1/2 x b x a.
