Question

A 45 degree is one fourth of a complete rotation true or false

Answer 1

A 45° is not one fourth of a complete rotation because 1/4 of 360° is 90. So the answer is false.

Answer 2

It is false :)

A complete rotation is 360 degrees. One fourth of that would be 90:

1/4 = 0.25 so

0.25 * 360 = 90

One fourth of a complete rotation is 90.
