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 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.
A hexagon has 6 sides. An octagon has 8 sides. Therefore an octagon has two sides more than a hexagon.
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
