In such cases, you would have to manually use the trigonometric functions so you can solve these missing lengths. This is why the theorem is also known as the hypotenuse formula which is: The credit for this theorem foes to Pythagoras, the mathematician, and philosopher of ancient Greece. A right triangle, sometimes called a right-angled triangle, is a triangle that has one interior angle equal to exactly 90 degrees, forming what is called a right angle. The calculator uses the following formulas to find the missing values of a right triangle: Pythagorean Theorem: $$ a^2 + b^2 = c^2 $$ Area: $$ A = \frac{a b}{2} $$ Trig. To calculate the length of a missing side, you can use a known side and the hypotenuse and rearrange the Pythagorean theorem to solve the missing variable. I'm 73 and vaguely remember it as semi perimeter theorem. Thus, in this type of triangle, if the length of one side and the side's corresponding angle is known, the length of the other sides can be determined using the above ratio. When we dealing with simple and complex trigonometry sin(x) functions, this calculator uses the law of sines formula that helps to find missing sides and angles of a triangle.
