The triad is the most common type of chord. A triad is a three-note chord built in thirds. There are four types of triads: major, minor, augmented, and diminished. Each has a particular pattern of major and minor thirds.

Minor triad: minor 3rd, major 3rd
Augmented triad: major 3rd, major 3rd
Diminished triad: minor 3rd, minor 3rd
