153 diagonals.
A polygon with 14 diagonals will have 7 sides
There are: 0.5*(682-(3*68)) = 2210 diagonals
An octagon has 8 sides and 20 diagonals so the question doesn't make sense

153 diagonals.
There are 560 diagonals by using the diagonal formula
A polygon with 14 diagonals will have 7 sides
There are: 0.5*(682-(3*68)) = 2210 diagonals
9 sides because a nonagon has 27 diagonals
An octagon has 8 sides and 20 diagonals so the question doesn't make sense
The diagonals of a square are perpendicular (they intersect and form right angles). But they are angles bisectors since they bisect each pair of opposite angles. A perpendicular bisector actually bisects a side of a figure.
a face
Face.
An 11 sided polygon has 44 diagonals
It is: 0.5*(n2-3n) = diagonals.
See if the diagonal measurements are equal, and see if the side lengths are equal. If both are true, it's a square. If only the diagonals are equal, it's a rectangle. If the diagonals are not equal, it's a non-orthogonal parallelogram.
