What do all the angles in a hexagon add up too?

The sum of the interior angles in a hexagon can be calculated using the formula ( (n - 2) \times 180^\circ ), where ( n ) is the number of sides. For a hexagon, ( n = 6 ), so the calculation is ( (6 - 2) \times 180^\circ = 4 \times 180^\circ = 720^\circ ). Therefore, all the angles in a hexagon add up to 720 degrees.
