Decagon exterior angles

In geometry, a decagon is known as a ten-sided polygon or ten-gon. A decagon is a ten-sided polygon with ten vertices and ten angles. Thus, a decagon shape can be defined as a polygon having ten sides, ten interior decagon exterior angles, and ten vertices. Based on the sides of a decagon, they are broadly classified into regular decagons and irregular decagons.

A regular decagon is a sided shape where every side is the same length and every corner has the same angle. All regular decagons have the same shape, like this:. An irregular decagon is a 10 sides shape where not every side and angle are equal. There are many different irregular decagon shapes, here is an example:. The name decagon is a combination of the words deca Greek meaning five and gonia Greek meaning corner. The interior angles of a decagon are shown here:.

Decagon exterior angles

A decagon is a sided polygon, with 10 interior angles, and 10 vertices which is where the sides meet. Polygons get their name from Greek, meaning "many-angled," because all polygons have multiple interior angles. They close in a two-dimensional space using only straight sides. Drawing a decagon takes no skill; simply draw 10 line segments that connect, and you have it. Drawing a concave decagon is actually fairly easy: make a five-pointed star and fill it in. That is the star that appears 50 times on the Unites States flag, and the outline of such a pentagram five-pointed star is a decagon. A regular decagon has 10 equal-length sides and equal-measure interior angles. All polygons can be drawn as regular equal-length sides, equal-measure interior angles or irregular not restricted to congruent angles or sides. Because it is a challenging shape to make, the regular, convex decagon is popular with coins like those from Australia, Belize and Hong Kong. Irregular decagons must simply have 10 sides closing in a space, but the lengths of their sides can vary greatly.

The classic regular decagon meets all these requirements:. Example 1 : Jenifer's hobby is collecting coins from various countries.

Home » Decagon. A decagon is a polygon with ten sides and ten angles. The below-given properties and formulas to find the perimeter and area only apply to the regular decagon. Find the perimeter of a regular decagon with each side measuring 5. Find the area of a regular decagon having each side measuring 8 cm. The angle formed inside the decagon at its corners when the line segments join in an end to end fashion. The total measure of all the interior angles combined in the decagon. The formula is given below:. The measure of one interior angle can be obtained by dividing the sum of the interior angles by the number of sides in a decagon. The angle formed by any side of the decagon and the extension of its adjacent side.

The name decagon is a combination of the words deca Greek meaning five and gonia Greek meaning corner. The interior angles of a decagon are shown here:. Where n is the number of sides. In this case, the number of sides n is 10, so the sum of the interior angles is:.

A decagon is a polygon with 10 sides and 10 vertices. A decagon gets its name from the Ancient Greek word "deka-" meaning "ten" and "gonia" meaning corner or angle. Thus, a decagon is a sided closed-figure with 10 corners and angles.
