The exterior angle of a regular polygon is one-third of its interior angle. How many sides has the polygon? View Solution Prove that the interior angle of a regular pentagon is three times exterior anles of a regular decagon. View Solution The interior angle of a regular polygon exceeds ...
If the difference between the exterior angle of an( n )sided regular polygon and an (n + 1) sided regular polygon is 12∘ find the value of n. View Solution Prove that the interior angle of a regular pentagon is three times the exterior angle of a regular decagon. View Solution Each...
A polygon of n sides have n vertices, and each vertex of a polygon has one interior angle. The sum of interior angles of a polygon of n sides are given according to the below formula: Sn=(n−2)180∘ where Sn is the sum of all interior angles of an n-sided poly...
For example, the square and decagon below can be rotated and copied to yield the small rhombidodecahedron shown above. So far, so good. But how do you represent the symmetries of a uniform polyhedron? Answering this question will be a major topic in this thread — I hope to walk you ...
