In geometry, a digon is a polygon with two sides (edges) and two vertices. Its construction is degenerate in a Euclidean plane because either the two sides would coincide or one or both would have to be curved; however, it can be easily visualised in elliptic space.
What do the 5 angles of a pentagon add up to?
FAQs on Angles in a Pentagon The sum of all the interior angles of a regular polygon can be calculated by the formula: Sum of angles = (n – 2)180°, where ‘n’ represents the number of sides. Substituting the value of ‘n’ in the formula: (5 – 2)180° = 540°. Therefore, all the 5 angles in the pentagon sum up to 540°.

Are circles infinite polygons?
If Pn is a regular n-sided polygon, then the limit of the sequence P1,P2,… is a circle. This statement is, basically, the statement “n-sided polygons approach a circle as n tends to infinity”, in mathematical terms.
