im not sure!!:(
If the octagon is not regular, the perimeter could have any value greater than 18 inches. If it is regular, then the perimeter is 8*18 = 144 inches.
An octagon has -2 [negative 2] more sides than a decagon.
An octagon has four more sides than a trapezoid, because an octagon has 8 sides whereas a trapezoid has 4 sides
An octagon has eight sides, while a quadrilateral has four sides. Therefore, an octagon has four more sides than a quadrilateral.
An octagon has more sides and angles than a pentagon. An octagon is a polygon with eight sides and eight angles and a pentagon is a polygon with five sides and five angles.
If the octagon is not regular, the perimeter could have any value greater than 18 inches. If it is regular, then the perimeter is 8*18 = 144 inches.
an octagon has three more sides than a pentagon
An octagon has -2 [negative 2] more sides than a decagon.
An octagon has four more sides than a trapezoid, because an octagon has 8 sides whereas a trapezoid has 4 sides
An octagon has 8 angles, a rhombus has 4. Therefore an octagon has 4 more angles
An octagon has more sides and angles than a pentagon. An octagon is a polygon with eight sides and eight angles and a pentagon is a polygon with five sides and five angles.
An octagon has 8 sides. A pentagon has 5 sides. So an octagon has 3 more sides than a pentagon.
A hexagon has 6 sides. An octagon has 8 sides. Therefore an octagon has two sides more than a hexagon.
an octagon is a polygon. an octagon has 8 sides. a polygon is a shape with closed sides.
An octagon has 8 sides and a quadrilateral has 4 sides.An octagon has 8 - 4 = 4 more sides than a quadrilateral.
16 * * * * * Not sure what a rectangular octagon is but no kind of octagon has more than 8 lines of symmetry.
an octagon has 8 sides and a hexagon has 6 sides so a octagon has 2 more sides then a hexagon hope this helped you
