It is a 2-dimensional (plane) figure that is closed and which is bounded by straight lines.
A polygon must be a plane, closed figure bounded by straight lines.
A hexagon is a plane figure bounded by six straight lines. That is not the same thing as 6.
A pentagon is a plane figure bounded by five straight lines. It does not equal 180 of anything.
No. A polygon is a plane area bounded by straight lines. The key term in this context is "plane". It is, therefore, 2 -dimensional shape. A solid, which is bounded by faces that are polygons, is called a polyhedron (plural = polyhedra).
A plane figure cannot be bounded by only one straight line. If the shape is bounded by lines which are not straight or by several straight lines the answer will depend on exactly what these are.
It is a plane figure bounded by 400 straight lines.
A dodecagon is a plane (2-dimensional) figure which is bounded by 12 straight lines.
Nothing. Though a heptagon is a plane figure bounded by seven straight lines.
It is a plane figure bounded by four straight lines, two of which are parallel.
It is a 2-dimensional (plane) figure that is closed and which is bounded by straight lines.
A polygon must be a plane, closed figure bounded by straight lines.
It means a plane geometric shape bounded by 12 straight lines.
A Polygon is a closed plane figure bounded by straight sides.Polygons is a plane figure with more than 3 straight sides and angles and are typically 5 or more.
A hexagon is a plane figure bounded by six straight lines. That is not the same thing as 6.
A trapezium is a plane figure, bounded by four straight lines. One pair of these lines is parallel, the other pair is not.
A pentagon is a plane figure bounded by five straight lines. It does not equal 180 of anything.
