Angles in decagon

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 angles in decagon, ten interior angles, and ten vertices.

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.

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. Now, let us start with the definition of a decagon and proceed with its formula for finding the number of sides and angles. From the above text, we understand that the decagon has all four things like sides, vertices, interior, and exterior angles as 10 in number. Below, you can find the important properties of a decagon that will be helpful for you to understand the types of decagons we will be discussing further:. There are 10 sides of a decagon. The sum of the measurements of all the exterior angles, i. A decagon shape has 35 diagonals.

Decagons in which all the sides and angles are equal are known as regular decagons. Have angles in decagon ever wondered what would a shape look like if it had ten sides?

Properties of decagons, interior angles of decagons. Using the same methods as for hexagons to the right I'll let you do the pictures To find the sum of the interior angles of a decagon, divide it up into triangles There are eight triangles Because the sum of the angles of each triangle is degrees We get. So, the sum of the interior angles of a decagon is degrees.

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. There are various types of decagons that can look quite different. Decagons only need to be closed, two-dimensional shapes with 10 sides, angles, and vertices. For this reason, they can take on many different shapes. The figure below shows a few decagon examples:. A regular decagon is one in which all sides and interior angles have the same measure. A regular decagon has 10 equal sides and interior angles. It is also always convex.
