Pythagorean theorem
The Pythagorean theorem states, that in any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs. The theorem can be written as an equation: a²+b²=c², where c represents the length of the hypotenuse, and a and b represent the lengths of the other two sides. Below you find the Pythagorean theorem depict with an oppurtunity to use it with your own values.
Trigonometric functions
From the Pythagoraen theorem you can assume to the trigonometric functions. These are defined as followed:
