Triads are chords made up of three notes. Triads can be major, minor, augmented, or diminished. The following examples show the structure of each of these chords:

major triads

Major triad: major 3rd, perfect 5th

minor triads

Minor triad: minor 3rd, perfect 5th

diminished triads

Diminished triad: minor 3rd, diminished 5th

augmented triads

Augmented triad: major 3rd, augmented 5th

Major and minor triads are considered to be perfect because they always have a perfect fifth. Diminished or augmented triads are called by the name of the fifth they contain.
