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.

An octagon has 8 sides. A decagon has 10. So 3*8+10 = 34 sides

How many sides do 4 dodecagons 3 pentagons and 2 decagons have in all?

There are 12 sides in a dodecagon, 5 in a pentagon, and 10 in a decagon. So in 4 dodecagons, 3 pentagons, and 2 decagons there are 4*12 + 3*5 + 2*10 = 48 + 15 + 20 = 83 sides altogether.


How many sides does a not regular decagon have?

It still has ten sides, same as a normal decagon. "Irregular" simply means that all the sides and angles of the decagon are not congruent.


How many sides does a regular decagons have?

It still has ten sides, same as a normal decagon. "Irregular" simply means that all the sides and angles of the decagon are not congruent.


How many sides and angles does a decagon have?

A decagon has 10 sides, and 10 angles. The sum of the interior angles of a decagon is (10-2)×180° = 1440° In a regular decagon all the angles are congruent at 1440° ÷ 10 = 144°


What is a shape whith 10 sides?

You just call it a decagon. If all the angles and sides are equal then it's a regular decagon. If not, it's an irregular decagon.


Shape ten sides?

The shape is called a decagon. If all the sides and angles are the same, it is called a regular decagon.


Does a decagon have 10 sides?

Yes, 10 equivalent sides! * * * * * Not true: the sides need not be equivalent or equal. It is only in the case of a REGULAR decagon that all the sides have to be of the same length AN all the angle must be the same measure.


Is a decagon a regular figure?

Any polygon is regular if its sides are all the same length, or irregular if they're not. If all 10 sides of your decagon are the same length, then you have a regular decagon. If they're not, then you have an irregular one.


What is the permeter of a regular decagon with 25cm sides?

Regular = all sides equal so all sides of 25 cm. Decagon = 10 sides. So perimeter = 10*25cm = 250 cm.


What is the sum of the measures of a decagon?

Add each side of the decagon, or all ten sides, to get the sum.


How do you make a decagon?

''Decagon'' is any polygon with ten sides and ten angles ''Regular decagon'' is a polygon with ten sides of equal length and all angles equal to 144°


What is the measure of one the interior angles of the regular decagon?

First of all, a decagon is a polygon with 10 sides. A regular decagon is a decagon in which all of the sides and angles are equal. Since there are 360o in a complete rotation, you can simply divide 360o by 10. 360o / 10 = 36o
