Exterior angle of decagon

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, exterior angle of decagon you have it.

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.

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.

Exterior angle of decagon

What is the total number degrees of all interior angles of a triangle? So, our new formula for finding the measure of an angle in a regular polygon is consistent with the rules for angles of triangles that we have known from past lessons. Substitute 8 an octagon has 8 sides into the formula to find a single interior angle. Substitute 12 a dodecagon has 12 sides into the formula to find a single interior angle. Substitute 16 a hexadecagon has 16 sides into the formula to find a single interior angle.

Privacy Policy. Properties of Decagon 4. Geometry Tutors Phoenix. In the case of an irregular decagon, we can simply add the side lengths to find the perimeter. Geometry Tutors Houston. Multiplication Tables. Irregular decagon has unequal sides. Decagon Examples Example 1 : Jenifer's hobby is collecting coins from various countries. Meaning of Decagon 2. Hence, we divide the total sum of the interior angles by While concave decagons have indentations a deep recess. A decagon can be recognized as a polygon with 10 sides, 10 interior angles, and 10 vertices. By joining one vertex to the remaining vertices of the decagon, 8 triangles will be formed.

Geometry Worksheet. There are three possible classifications of decagon that are given below:. By joining one vertex to the remaining vertices of the decagon, 8 triangles will be formed. Example 2 : What is the perimeter of a regular decagon if the length of a side is 4 units? Meaning of Decagon 2.
