text: The minimum number of triangles created in our hexagon, by drawing three diagonals, is four; each triangle has interior angles adding to 180 ° , so the sum of the interior angles of a regular hexagon is 4 × 180 ° , or 720 ° .
text: The internal angles of a triangle always add up to 180°.
text: The angles within each triangle add to 180 degrees.
text: The interior and exterior angles will always add to 180 ° , so they are supplementary.
text: Together, the adjacent interior and exterior angles will add to 180 ° .
text: You can divide any quadrilateral into two triangles, and the angles in each triangle add up to 180°, so all the angles in the quadrilateral must add up to twice that, 360°.
text: The following diagram shows a regular hexagon: Note that, for any point in a polygon, the interior angle and exterior angle are on a straight line and therefore add up to 180°.
