The total interior angles of a hexagon = 720°
Each time we add a side (triangle to square, square to pentagon, pentagon to hexagon) we add another 180°.

The total internal angles of a hexagon = 720°
Now divide the total internal angle by the number of corners.
i.e. divide 720° by 6.
`720^circ/6=120^circ`
