1. Initiate with a Circle: Begin by drawing a circle of the desired radius using the compass. 2. Determine the Central Angle: The central angle is crucial and is given by the formula: Central Angle \ (= \frac {360^\circ} {n}\) Where \ (n\) is the number of sides of the regular polygon. 3. Constructing Polygon Vertices:

Regular Polygon in a Circle Author: AMW0ng, David Griswold Topic: Circle Enter a number of sides (from 3 to 360), use the slider, or use the next and prev buttons to inscribe a regular polygon in the circle of radius 7 provided. The Apothem (the dashed line in the applet below) is the length from the center of the regular to one of its sides.

Regular pentagons Side ( ), circumradius ( ), inscribed circle radius ( ), height ( ), width/diagonal ( ) A regular pentagon has Schläfli symbol {5} and interior angles of 108°. A regular pentagon has five lines of reflectional symmetry, and rotational symmetry of order 5 (through 72°, 144°, 216° and 288°).

To inscribe a regular pentagon in a circle, first draw perpendicular radii OA and OB from the center O of a circle. Let C be the midpoint of OB and draw AC. Bisect angle ACO to meet OA at D. Draw a perpendicular DE to OA to the circle. Then AE is one side of the pentagon. The remaining sides can then be constructed.

Inscribing a regular pentagon in a circle - and proving it Scott E. Brodie Constructions by straight-edge and compass of several regular polygons - the equilateral triangle, square, hexagon, and octagon, are familiar. Indeed, the construction of an equilateral triangle is the very first proposition in Euclid's Elements (I.1).

In this video, I'll show you how to construct a regular pentagon given the diameter of the circumscribing circle.
Solved A regular pentagon is inscribed in a circle of radius
Area A of a regular pentagon can be calculated from the formula: area = a² × √ (25 + 10√5) / 4, where a is a side of a regular pentagon. Also, you can find the area having the circumscribed circle radius: area = 5R² × √ [ (5 + √5)/2] / 4, where R is the circumcircle radius.

$\begingroup$ Using that angle and radius 1, the answer is (one side of the pentagon) $ 2 \sin{\pi /5}$. My first answer was thinking on the other angle, eache intern angle of the pentagon is 108 degrees, that one is half of it, so is 54 degrees since the side is the adjacent to that i use $2 \cos{54}$, gives the same answer $\endgroup$ -

b. Now you are going to prove the claim: HK is the side length of a regular pentagon inscribed in a circle of radius 1. First convince yourself by using GeoGebra to construct such a pentagon in the circle from part (a) (use straightedge and compass only). In the parts below, you will prove this by (I) computing the length of HK and (II.
