Right angle

It is based on the most widely known Pythagorean triple 3, 4, 5 and so called the "rule of 3-4-5". From the angle in question, running a strht line along one side exactly 3 units in length, and along the second side exactly 4 units in length, will create a hypotenuse the longer line opposite the right angle that connects the two measured
