Hi! I have a doubt on heptagons,octagon, nonagon& decagon. How many diagonals do they have? How to draw them?
We can use formula to find number of distinct diagonals .
Number of diagonals of n - sided polygon =
Number of diagonals of heptagon ( We know in heptagon we have 7 sides , So n = 7 ) = = 14
Number of diagonals of octagon ( We know in octagon we have 8 sides , So n = 8 ) = = 20
Number of diagonals of nonagon ( We know in nonagon we have 9 sides , So n = 9 ) = = 27
Number of diagonals of decagon ( We know in decagon we have 10 sides , So n = 10 ) = = 35
We can draw these diagonals by joining each non consecutive vertices.
Here we have draw diagonals of heptagon , As :
You can try to draw diagonals for different polygon by yourself and if still have any doubt , Kindly get back to us so we can help you precisely .
