Constructing a Regular Pentagon within given Circle By Using Ruler and C... Pentagon, Ruler
Math 311. Regular Polygons Name: A Candel CSUN Math The Pentagon There are several methods of constructing a regular pentagon with ruler and compass. ¶ 5. Given a circle with center O through A, follow these steps to construct a regular pentagon inscribed in OA. (a) Let AB be the diameter of OA through A. (b) Let E be the midpoint of OA.
How to draw a regular pentagon knowing the length of one side YouTube
A regular pentagon is a five-sided polygon with sides of equal length and interior angles of 108° (3π/5 rad). Because 5 is a Fermat prime, you can construct a regular pentagon using only a straightedge and compass. Steps Download Article 1 Draw a line segment AB. [1] 2 Draw two circles, 1 and 2, centred at A and B, both with radius AB.

$\begingroup$ 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 $\endgroup$ -
Pentagon Wikipedia
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.

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).

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.

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.
