104 is the size of obtuse angle DOF because the angle at the center is twice the angle at the circumference.
What is an obtuse angle?
An obtuse angle is any angle greater than 90 °: Straight angle is a measurement angle equal to 180 °: Zero angles is a measurement angle equal to 0 °: Complementary angle is the angle at which the sum of the measurements is 90 °: Complementary angles are the following angles: The total dimensions are 180 °.
Now we know that angles below 180 degrees and above 90 degrees are obtuse. Examples of bluntness include 110 °, 135 °, 150 °, 179 °, 91 °. Therefore, all angles in the range of 90 ° to 180 ° are obtuse.
