**How to calculate the area of an octagon Quora**

Thus the side length is equal to the radius of the circumscribed circle. It is not amazing, because the central angle of the regular hexagon is 60°, and the isosceles triangle formed by the two radii and the side of the hexagon is the equilateral triangle. how to choose a good primary school in sydney TopOctagon can be defined as a Polygon that has eight sides and eight angles. Each interior angle of octagon measures 135 degree, and sum of all angles of an octagon (eight angles) is 1080. Now we will see how to make an octagon. We need to follow some steps to draw an octagon.

**Draw an octagon with an area of 18 square centimeters**

Find the length of one side, the perimeter and area of a regular octagon given the distance between two opposite sides (span). Solution to the Problem: The octagon has 8 interior angles. The measure of one interior angle ABD is given by (8 - 2)*180 / 8 = 135 degrees Draw AC and BC so that they are perpendicular at C. Hence the measure of ABC is given by 135 - 90 = 45 degrees Note that triangle how to draw a cute girl and boy Regular hexadecagon. A regular hexadecagon is a hexadecagon in which all angles are equal and all sides are congruent. Its Schläfli symbol is {16} and can be constructed as a truncated octagon, t{8}, and a twice-truncated square tt{4}.

- If like me you are confused by algebra but ok with trigonometry. Look at the lower sector of the octagon first, (see figure below). Divide the sector to make two right angle triangles, the lower angle is 67.5 degrees. using ten as an example of side length the half sector base is 5 units.
