These intervals are called “perfect” most likely due to the way that these types of intervals sound and that their frequency ratios are simple whole numbers.
Also, Why is it called perfect fourth?

Herein, What is the fourth note? The fourth note is called the subdominant. Notice that the subdominant is the same distance below the tonic as the dominant is above it (a generic fifth). The prefix sub is Latin for “under” or “beneath”. The third note is called the mediant since it is in the middle of the tonic and dominant.
Why is it called perfect fifth?
The term perfect identifies the perfect fifth as belonging to the group of perfect intervals (including the unison, perfect fourth and octave), so called because of their simple pitch relationships and their high degree of consonance.

What is the purpose of Circle of Fifths?
The circle of fifths is a useful method for organizing key signatures and the progression of sharps and flats. The progression of sharps and flats follows the circle. We begin at the top of the circle with C major (zero sharps and zero flats). As we progress clockwise around the circle, we add 1 sharp.
What is the perfect fifth above D?
For example, in the steps above, one of the intervals we measured was a perfect 5th above D, which is note A. In contrast, an inverted interval specifies the distance from A to D – ie. note D is above note A.
Why does a perfect fifth sound good?
The perfect 5th has the simplest form with the fewest peaks and valleys, making a smooth sounding tone. More peaks and valleys in a tone we will hear as a dissonance or “grinding” sound. The only thing smoother than the 5th would be an octave, or 2:1 ratio.

What is Circle of Fifths in music?
The circle of fifths is a sequence of keys (and their root chords) graphically represented in a circle, where each key or chord is seven semitones away from the key or chord next to it in the circle. Most circles of fifths begin with a C major at the top of the circle.
