Really clear math lessons (pre-algebra, algebra, precalculus), cool math games, online graphing calculators, geometry art, fractals, polyhedra, parents and teachers areas too. Hexagons can even tessellate, because the 120 degree angles add up to 360. But pentagons have 108 degree angles. Three of them add up to 324, only leaving 36 degrees left to close the circle Here is a non-regular hexagon: We can slide the angles over in the same way, to show that they add up to \(360^{\circ}.\) Method 2. This is one way to "see" it inside your head. Another way to prove that the sum of the exterior angles of a polygon is \(360^{\circ}\) is to use a different method: to chop up the septagon into triangles. If it is a Regular Polygon (all sides are equal, all angles are equal) Shape Sides Sum of Interior Angles Shape Each Angle; Triangle: 3: 180° 60° Quadrilateral: 4: 360° 90° Pentagon: 5: 540° 108° Hexagon: 6: 720° 120° Heptagon (or Septagon) 7: 900° 128.57...° Octagon: 8: 1080° 135° Nonagon: 9: 1260° 140°..... Any Polygon: n (n−2) × 180° (n−2) × 180° / n Hint: the angles in a triangle add up to 180°. Angles that meet on a line also add up to 180°. By refreshing the page you can try different versions of the questions. The easiest way to calculate the total of the interior angles is from knowing that every, absolutely every, polygon’s external angles add up to 360 degrees, therefore, taking the hexagon as an example, its external angles average out at 360/6 degrees or 60 degrees. that being so, the internal (supplementary) angles average out at 120 degrees, and, since there are six internal angles averaging 120 degrees, they add up to 120 x 6 or 720 degrees total. for a regular hexagon, all angles would add up to 720 or each one is 120. for an irregular hexagon all the angles still add up to 720 but not all the angles, if any, will be 120 An easy way to do this is to remember that the *exterior angles* of a polygon always add up to 360°. So one exterior angle of a regular hexagon will be 360°/6 = 60° The interior angle is always the... exterior angles in a pentagon and hexagon add up to 360*(5+6)/5*6 degrees = 132 degrees as each exterior angle in pentagon is 360/5 and in hexagon is 360/6.
