The Pythagorean triangle was named after Pythagoras, a Greek mathematician and philosopher. The triangle is named after Pythagoras because it is a special kind of triangle, which is called a right triangle. A right triangle is a triangle that has one right angle, meaning that the sum of the two angles opposite to the right angle is 180 degrees. The other two angles in a right triangle are called the acute and obtuse angles.
