The B♭ major triad consists of a root (B♭), third (D), and fifth (F). The distance between the root and the third is a major third interval (or four half-steps), and the distance between the third and the fifth is a minor third interval (or three half-steps). Major triads have a “happy” sound.

Chord Symbol: B♭7
A dominant 7th chord is a major triad with an added seventh, where the distance between the root and the seventh is a minor 7th interval.
You can also think of dominant 7th chords as being built on the fifth note of a major scale and following that scale’s key signature. For example, B♭7 is built on B♭, the fifth note of E-flat major, and follows E-flat major’s key signature (B♭, E♭, A♭).
Chord Symbol: B♭dim7
A diminished 7th chord is a four-note-chord where each note is a minor third apart. You can think of diminished 7th chords as a “stack of minor thirds.”
Chord Symbol: B♭m7♭5
The half-diminished chord is also called the “minor seven flat five” chord. It is a minor 7th chord where the fifth is lowered by a half-step.
