use on non right triangles

The pythagoras theorem can also be used in other type of triangles that are not right that means it doesnt have a 90 degree angle . but how do you do it? you can do it by dividing the normal or non right triangle into two right triangle then you make the same process of the pythagoras theorem, for both of them, that is a A squared plus B squared equals c squared it means that if you make a square with one side as the leg of the small right triangle and you add that square to a square that one side is the other leg. then the answer will be the square that one side will be the hypotenuse. then if you want to find the length of the hypotenuse find the squared root of the square and add the sides that are needed to add for example:
