If squares are constructed all internally or all externally on the sides of an octagon. 9 therefore the sum of the all exterior angle of an octagon = 360°. .exterior angle , heptagon , hexagon , interior angle , leg , median , nonagon , opposite sides , octagon , parallelogram , pentagon diagonal sum.

How will you get the sum of 8 interior angles of a concave irregular octagon using following figure?

Each angle (of a regular polygon) = (n−2) × 180° / n. To find the measure of the angles, we know that the sum of all the angles is 1080 degrees (from above). For a regular octagon with 8 sides, the sum of the interior angles would be: If squares are constructed all internally or all externally on the sides of an octagon.

But sum of all the n exterior angles =360∘ ⇒n×70∘=360∘ ⇒n=70360 =571 =a whole number hence, a regular polygon having measure of each interior angle 110∘ can not exist.

To see how it works, first draw yourself an octagon (it doesn't have to be perfect).

The sine of the sum and difference of two angles is as follows we will prove the cosine of the sum of two angles identity first, and then show that this result can be extended to all the other identities.

Because there are 8 vertices in an octagon , the sum of all the internal angles will be 8*135 = 1080 degrees.
