`(pi)/(4)` is 45°, so the complementary angle is what you need to add to 45° to get 90°, which is 45°, while the supplementary angle is what you need to add to 45° to get 180°, that is to say 135°

Given

`pi/4 = 180^@ /4 =45^@`

so the complementary angle of `45^@ = 90- 45 =45^@ = pi/4`

supplimentary angle of `45 ^@ is = 180-45 =135^@= (3*pi)/4`
