How many sides does it have if a polygon has 27 diagonals?
The polygon has 9 sides.
What polygon has 23 diagonals?

Does a Nonagon have 27 diagonals?
Diagonals of nonagon There are 6 diagonals extending from each of the 9 vertices of the nonagon above creating a total of 27 diagonals.
Which polygon has 27 diagonals?
It is a Nonagon.
How many diagonals are there in Pentagon?
five
Polygons: How Many Diagonals? (For pairs or groups of students) A diagonal of a regular polygon is a straight line joining two vertices which are not adjacent. Thus a square has two diagonals, and a regular pentagon has five, as shown below.
What is shaped like a nonagon?
An irregular nonagon is a nine-sided shape that does not have equal sides or angles. One real world example of an irregular nonagon is the US Steel Building in Pittsburgh, Pennsylvania. It looks like a triangle with each corner indented.
How many diagonals does Dodecagon have?
54 diagonals
Therefore, there are 54 diagonals in a dodecagon….Triangles in a Dodecagon.

Is nonagon a polygon?
In geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon. The name nonagon is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.

How many sides does a polygon have 27 diagonals?
It is given that the polygon have 27 diagonals. n should not be negative so 9 is the number of sides. So the polygon have 9 sides which is also called a nanogon. Originally Answered: A polygon has 27 diagonals. How many sides does it have?
How do you find the number of sides of a polygon?
We know that, to find diagonals of a polygon, we use the formula n(n-3)/2 where n is the number of sides. It is given that the polygon have 27 diagonals. n should not be negative so 9 is the number of sides. So the polygon have 9 sides which is also called a nanogon.
How do you find the number of diagonals of a triangle?
The formula for the no. of diagonals of a ’n’ sided polygon is n (n-3)/2 . It works for triangle (0 diagonals) , quadrilateral (2 diagonals) , pentagon (5 diagonals) and for every another polygon. Let’s come to the problem. No. Of diagonals = n (n-3)/2 = 27
