Explain Right Triangle Protractor

Introduction:
         A right triangle, (also called a right-angled triangle), has one angle that is 90 degrees. The other two angles always add up to 90 degrees but can be different sizes. The side opposite to the right angle is the hypotenuse; it is the longest side in the right triangle
Define protractor:
       In geometry, a protractor is a circular or semicircular tool for measuring an angle or a circle. The units of measurement utilized are usually degrees.
                                           

More about Right Triangles: 

The Pythagorean Theorem for right triangles:

             This is due to finding right triangle in large quantity in the physical structures of the world around us and the importance of finding perpendicular distance. The very important tools in right angle triangle problem are the Pythagorean Theorem. Proofs that are more different have been written for the Pythagorean Theorem than for any other theorem in geometry. Pythagoras is given credit for developing the subsequent proof based on similar triangles.
