Decagon/Number of vertices

How do you find the sides of a decagon?

Dale, In the diagram below the length of AC is 5 feet, the angle ABC has measure 144/2 = 72 degrees and the angle CAB is a right angle. |AB| = 5/tan(72o) = 1.62 feet. Hence the length of a side of the decagon is 2 × 1.62 = 3.24 feet.

How many degrees are in a decagon?

1440°
Decagon/Sum of interior angles

How much sides does a dodecagon?

A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.

What is a Nonagon shape?

Definition of a Nonagon A nonagon is a nine-sided polygon. You may recall that a polygon is a many-sided shape. We use the suffix -gon to indicate the number of sides of a polygon. Here are some commonly used polygon names: Name.

How many conguent sides does a regular decagon have?

Regular decagon or 10-gon: 10 sides : 100 interior angles of 176.4° 100 exterior angles of 3.6° Any polygon that does not have equal-length sides along with equal interior and exterior angles is an irregular polygon; it goes on the discount shelf! Our hexagon has six congruent sides . It has six equal interior angles,

How many diagonal lines does a decagon have?

For a diagonal to be formed, 2 vertices are required. Thus in a decagon there are 10 sides. And no.of lines can be formed are 10C2 ( C combinations -Permutations and Combinations) but in 10C2 the sides are also included.

How many parellel sides does a decagon?

Decagon Definitions A decagon is a 10-sided polygon, with 10 interior angles, and 10 vertices which is where the sides meet. A regular decagon has 10 equal-length sides and equal-measure interior angles. Each angle measures 144°
