Polygons are closed, two-dimensional figures that have 3 or more sides.
A quadrilateral
A straight line has no right angles. But a square is actually a closed line with four right angles.
More than 3 sides, closed figures, and, straight sides.
They are plane figures They are closed They are bounded by 3 or more straight sides They have the same number of sides as vertices Their exterior angles add to 360 degrees Their interior angles add to (n-2)*180 degrees, where n is the number of sides
A polygon is any closed plane figure bounded by three or more straight sides.
Polygon
polygon: it refers to a figure that has closed sides and straight edges with more than 3 sides
A quadrilateral
A straight line has no right angles. But a square is actually a closed line with four right angles.
They are closed plane figures bounded by straight lines.
More than 3 sides, closed figures, and, straight sides.
Polygons are closed plane shapes bounded by straight lines.
They are plane figures They are closed They are bounded by 3 or more straight sides They have the same number of sides as vertices Their exterior angles add to 360 degrees Their interior angles add to (n-2)*180 degrees, where n is the number of sides
Basically, the meaning of a polygon is closed because the sides are straight. A meaning of a polygon for you: a square. A square has 4 sides that are all straight, a square is a polygon.
Three straight sides Closed figure two dimensional three angles
A quadrilateral - if the sides are straight lines.
They are closed plane figures bounded by straight lines that do not cross each other.
