Why is there 360 degrees why not another number?

Answer 1

Because the ancient mathematicians who were doing work with circles decided that 360

would be a good number to use to define one complete revolution (or circle).

In that way, they could split up the whole thing into 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24,

30, 36, 40, 45, 60, 72, 90, 120, or 180 equal pieces without ever using fractions of degrees.
