What is true of it

A7 is A, C♯, E and G — 1, 3, 5 and b7 counted from A.

On an instrument that cannot reach all 4, the 5 goes first, in that order.

The easiest of the 5 fingerings below is x02020: 2 fingers, held at the 2nd fret.

2 of them use open strings, which is what makes a shape quiet to change to.

1 string stays silent.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
