A heptagon can have 7 lines of symmetry but it need not have any.
It will have 7*(7-3)/2 = 7*4/2 = 14 diagonals.
It has 7 lines of symmetry
A heptagon can have 0, 1 or 7 lines of symmetry.
A heptagon has seven sides, so a regular heptagon has seven lines of symmetry (they run from each vertex to the middle of the opposite side).
An irregular 7 sided heptagon normally has no lines of symmetry depending how it is constructed.
There are 14 diagonals in an heptagon
A heptagon can have 0, 1 or 7 lines of symmetry. 7 only if it is a regular heptagon.
It has 7 lines of symmetry
In a regular heptagon, there are 7 lines of symmetry because there is one line of symmetry for every side.
A heptagon can have 0, 1 or 7 lines of symmetry.
sevenImproved Answer:-14 diagonals
In a heptagon there is 14 diagonals
A heptagon has seven sides, so a regular heptagon has seven lines of symmetry (they run from each vertex to the middle of the opposite side).
There is no such word as a "hepticgon". A heptagon can have 0, 1 or 7 lines of symmetry.
It can have none or one.
It need not have any; it can have seven.
how many diagonals from a vertex a heptagon have
An irregular 7 sided heptagon normally has no lines of symmetry depending how it is constructed.
