It's to do with The Greek mathematician called Pythagoras. He was into trangles, particulary right angles ones, where he came up with a theory that relates the lengths of each side in a right angle triangle.

With right angle triangles
To determine if a shape is a right triangle, you need to check if one of its angles measures 90 degrees. Alternatively, you can apply the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides (a² + b² = c²). If either condition is met, then the shape is a right triangle.
Yes is you are using only straight ines, no if you are using arc segments.
To find the unknown side length of a shape, you can use various mathematical principles depending on the shape and known information. For triangles, you might apply the Pythagorean theorem or trigonometric ratios if you have angles and one side. For polygons, you could use properties like the sum of interior angles or the relationships between sides. Additionally, algebraic equations can be set up if you have sufficient information to solve for the unknown length.
