42 - Department of Mathematics
If you try to get several regular polygons to meet snugly at a point in the plane, what's the most sides any of the polygons can have? The answer is 42. The picture shows an equilateral triangle, a regular heptagon and a regular 42-gon meeting snugly at a point.
Regular heptagon - Wikipedia
A regular heptagon, in which all sides and all angles are equal, has internal angles of 5π/7 radians (128 4⁄7 degrees). Its Schläfli symbol is {7}. The area (A) of a regular heptagon of side length a is given by: cot ≃ 3.634 {\displaystyle A= {\frac {7} {4}}a^ {2}\cot {\frac {\pi } …
What is the sum of the angles of a 42 sided polygon - Brainly
2020年12月19日 · In geometry, a tetracontadigon (or tetracontakaidigon) or 42-gon is a forty-two-sided polygon. (In Greek, the prefix tetraconta- means 40 and di- means 2.) The sum of any tetracontadigon's interior angles is 7200 degrees. Step-by-step explanation: Internal angle (degrees): ≈171.429° Dual polygon: Self. Symmetry group: Dihedral (D42), order 2×42
Regular polygon - Wikipedia
In Euclidean geometry, a regular polygon is a polygon that is direct equiangular (all angles are equal in measure) and equilateral (all sides have the same length). Regular polygons may be either convex or star.

What is the measure of an interior angle of a regular 42-gon
2022年4月28日 · So the sum of the interior angle measures in a decagon is (10 − 2) • 180°, or 8 • 180° = 1440°. This is a regular decagon, so all ten interior angles are congruent. To...
Regular n-gon calculator and theory - Calcresource
2024年3月8日 · This tool calculates the basic geometric properties of a regular n-gon, that is a polygon having n sides and n vertices. Regular polygons are equilateral (all sides equal) and also equiangular (all interior angles equal).
POLYGON ANGLE CALCULATOR - onlinemath4all
The calculator given in this section can be used to know the name of a regular polygon for the given number of sides. And also, we can use this calculator to find sum of interior angles, measure of each interior angle and measure of each exterior angle of a regular polygon when its number of sides are given.
