What is the pythagorean theorem if segment is 5 cm and is a isosceles triangle?
The Pythagorean Theory applies to right angle triangles. If your isosceles triangle happens to also be a right triangle, the formula is a² + b² = c² where a and b are the sides and c is the hypotenuse. To calculate the length of a side, it is necessary to know which side the 5cm segment refers to (either side or the hypotenuse).
