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.

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:. Where n is the number of sides.

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.

All polygons can be drawn as regular equal-length sides, equal-measure interior angles or irregular not restricted to congruent angles or sides.

Wiki User. Sum of exterior angles of a polygon is o. Exterior and interior angles are supplementary, that is sum to o. If all the exterior angles of a hexagon or any polygon equal , then just divide by the number of vertices and there's one exterior angle of the polygon. A vertex is the same as an angle. A decagon has The total exterior angles of a polygon is always deg. Each interior angle plus its corresponding exterior angle is deg. The sum of all interior plus all interior for a decagon must therefore be deg.

Decagon exterior angles

All angles are classified based on whether they are found inside or outside of any geometric shape into interior and exterior angles. Angles that are found inside or within any geometric shape are called interior angles. They are also sometimes called internal angles.

Notice that a single decagon can fit into several categories. Geometry Tutors Chicago. Geometry Tutors Indianapolis. When any shape is formed by joining 10 sides, it is called a decagon. AP Calculus Tutors near me. Thus, a decagon shape can be defined as a polygon having ten sides, ten interior angles, and ten vertices. 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. Drawing a decagon takes no skill; simply draw 10 line segments that connect, and you have it. Solution: Decagon has ten sides and ten angles.
