The intervals that combine to make major, minor, and diminished triads are diagrammed here.

m3-minor third
M3-Major third
P4- Perfect fourth
b5-diminished fifth
P5- Perfect fifth
m6-minor sixth
M6-Major sixth

Triads are spelled every other letter from their root: C E G

C E G : The voicing with the chord's root in the bass is called the root voicing.
E G C : The 1st inversion has the third (E) of the scale in the base.
G C E : The 2nd inversion has the fifth (G) of the scale in the base.

The triads in this diagram are all closed voice, meaning there's not more than an octave between the bottom and top notes.

C Major, CEG, is the example here for major triad inversions,
D minor, DFA, is the example for minor inversions, and,
B diminished, BDF, is the example for diminished.

The triad inversions are notated with figured bass symbols:
The (6) is not a symbol for a Major 6th chord,
it describes how the bass is a 6th below the top note in the triad.
The (6,4) again describes the bass being a 6th below the top, and also describes that the bass is an augmented 4th below the next note in the chord.

Improvisations were played in Baroque music with figured bass notation.
