Decagon exterior angles

A regular decagon is a sided shape where every side is the same length and every corner has the same decagon exterior angles. 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, decagon exterior angles. There are many different irregular decagon shapes, here is an example:.

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.

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 angles, and ten vertices. Based on the sides of a decagon, they are broadly classified into regular decagons and irregular decagons. A regular decagon has 35 diagonals and 8 triangles. The location of these diagonals and triangles is explained in the later sections of this article. Decagons can be categorized as regular and irregular decagons based on side-length and angle measurements. There are three possible classifications of decagon that are given below:. A regular decagon is a polygon along with10 equal sides and 10 vertices. The sides and angles are congruent in a regular decagon. The characteristics of a regular decagon are:.

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

Have you ever wondered what would a shape look like if it had ten sides? We, on our every day life, see different shapes, for example, a window has four sides, a triangle has three sides and a pentagon has five sides. Similarly, a shape having 10 sides is called a decagon. We also define decagon as the polygon having ten sides, ten interior angles , ten exterior angles, and ten vertices. For example, the shape of a star has 10 sides, 10 vertices, which clearly indicates that the star is a decagon. Various types of decagons we study in mathematics. Here, on this page, we will focus on three types which are regular and irregular decagon, convex and concave decagon, and simple and complex decagon.

There is a formula to find the sum of interior angles of the n-sided polygon [ n-2 ] where n is equal to the number of sides. Irregular decagons must simply have 10 sides closing in a space, but the lengths of their sides can vary greatly. Decagon Examples Example 1 : Jenifer's hobby is collecting coins from various countries. Fact-checked by Paul Mazzola. An irregular decagon does not have equal sides and angles. There is no formula to find the area of an irregular decagon, but we can divide it into triangles and try to find the area of all triangles and add them. AP Statistics Tutors near me.
