How many diagonals are in a 7 sided polygon?

A 4-sided polygon has 2 diagonals. A 5-sided polygon, 5. 6-sided, 9. By induction, an n-sided polygon has 'n*(n-3)/2' diagonals. "n" is how many sides a shape has. so, (7)*(7-3)/2 now we have, 7*4/2 so, 28/2 = 14 Therefore, a 7-sided polygon would have 14 diagonals.


How many diagonals are in a 14 sided polygon?

The formula for finding the amount of diagonals in a polygon is n(n-3)/2. So 14(14-3)/2 = 77 Diagonals


Diagonals in a heptagon?

A polygon with n sides has n*(n-3)/2 diagonals.For a heptagon, that gives 14 diagonals.


How many diagonals in a heptagon?

12 * * * * * Not so. A polygon with n sides has 1/2*n*(n - 3) diagonals. In this case, n = 7 and so there are 14 diagonals.

A tetra-decagon is a 14 sided polygon having 77 diagonals


How many diagonals a heptagon has?

6 * * * * * No! The number of diagonals in a polygon with n sides is 1/2*n*(n - 3). So when n = 7 this gives the number of diagonals in a heptagon is 14.


How many diagonals does a septagon have?

There are 14 diagonals in a septagon. Another name for a septagon is heptagon. This is a seven-sided polygon. To figure the numbers of diagonals, you can use the formula 1/2 x [n x (n-3)], where n is the number of sides.

A polygon has fourteen vertices How many sides does the polygon have?

Fourteen. Each polygons has the same number of sides as it has vertices. Therefore, a polygon with 14 vertices must have 14 sides.


Can a polygon have exactly 10 diagonals-?

A polygon with n vertices has n*(n-3)/2 diagonals.A hexagon (n = 6) has 6*3/2 = 9 diagonals whilea heptagon (n= 7) has 7*4/2 = 14 diagonals.If a polygon were to have exactly 10 diagonals it would have to have between 6 and 7 sides. This is clearly impossible, and so a polygon cannot have exactly 10 sides.


How many sides on a tetra decagon?

A tetradecagon is a polygon that has 14 sides


Which is the regular polygon are the diagonals double the number of sides?

The number of diagonals in a polygon with n sides is n*(n-3)/2 This is double the number of sides so n*(n-3)/2 = 2*n That is n*(n-3) = 4n Dividing both sides by n gives (n-3) = 4 So that n = 7. A heptagon has 7*4/2 = 14 diagonals.


How many diagonals on a shape that has seven sides?

There are 7*(7-3)/2 = 7*4/2 = 14 diagonals.
