How many diagonals that can be drawn in an octagon?
0.5*(82-24) = 20 diagonals
How many sides does a n side polygon have?
An n-sided polygon or n-gon, just like it sounds, has n sides. For example, a 13-sided polygon has 13 sides. A 24-gon has 24 sides.
Why do you subtract 2 when calculating the interior degrees of a 24 sided polygon?
Basically when you have a 24 sided polygon you can split it up into 22 separate, non-overlapping triangles by drawing diagonals. Each triangle has 180 degrees, so the product, 22 times 180, gives you the sum of the interior angles of the 24 sided polygon.
What is the interior angle of a twenty-four-sided polygon?
If the polygon is regular, the measure of one interior angle of a 24 side polygon is 165 degrees.
How many sides does a polygon have if the exterior angle is 15 degree?
Providing that it's a regular polygon then: 360/15 = 24 sides
How many diagonals in nonagon?
24 diagonals
How many diagonals are in a 24-gon?
252 diagonals
How many diagonals that can be drawn in an octagon?
0.5*(82-24) = 20 diagonals
How many sides does a n side polygon have?
An n-sided polygon or n-gon, just like it sounds, has n sides. For example, a 13-sided polygon has 13 sides. A 24-gon has 24 sides.
How many diagonals does a 8 sided polygon have?
An eight-sided polygon has 8 vertices. Consider1st vertex = 7 diagonals to other vertices2nd vertex = 6 diagonals to other vertices (since one has now been used)3rd vertex = 54th vertex = 45th vertex = 36th vertex = 27th vertex = 18th vertex = 0, so7+6+5+4+3+2+1 = 28Improved Answer:-Formula for finding diagonals of a polygon 0.5*(n2-3n) when n is the number of sides0.5*(82-24) = 20 diagonals

A regular polygon measures 24 how many sides does the polygon have?
15
What is the interior angle of a twenty-four-sided polygon?
If the polygon is regular, the measure of one interior angle of a 24 side polygon is 165 degrees.
How many lines of symmetry in a 24 sided regular polygon?
24
How many triangles are in a 24 sided polygon?
There are 22
How many sides does an irregular polygon have if it has 252 diagonals showing work?
Let its sides be x and rearrange the diagonal formula into a quadratic equation:- So: 0.5(x^2-3x) = 252 Then: x^2-3n-504 = 0 Solving the quadratic equation: gives x a positive value of 24 Therefore the polygon has 24 sides irrespective of it being irregular or regular
How many sides does a polygon have if the exterior angle is 15 degree?
Providing that it's a regular polygon then: 360/15 = 24 sides
