How many degrees in a hexagon?

Answer 1

It is important to formulate the question correctly, because a lot of the time the questions are made to see if the student understands the terms.

A regular hexagon has six equal sides, the interior angles are all 120°, and the exterior angles (supplement of the interior angle) are 60°. There are six axes of symmetry, 3 of which pass through the vertices, and the other three are perpendicular bisectors of of the sides.

Now back to the question: How many degrees in a hexagon?
A hexagon does not have to be regular, which means that the sides do not have to be equal, nor the sides. There are many angles possible, the interior angle, meaning the obtuse angle between two adjacent sides, or the exterior angle made by one side and the extension of the adjacent side.
