A polygon would seem to fit the given description
They are closed plane figures bounded by straight lines.
All polygon sides are segments of lines.
A trapezoid/trapezium is a quadrilateral (4 sided shape) with exactly one pair of parallel sides.It is a quadrilateral (a closed plane shape with four linear sides) that has at least one pair of parallel lines for sides
Yes. The set of real numbers is closed under addition, subtraction, multiplication. The set of real numbers without zero is closed under division.
division
A closed plane figure, for example, a sector of a circular or elliptical shape has no specific name.
triangel
A polygon.
A Triangle :)
a triangle
a shape. The real answer is a polygon as long as the lines do not intersect anywhere but the endpoints. It could also be called a figure.
regular polygon-all the sides are the same length and the angles have the same measurement. polygon-a closed plane figure whose sides are segments that intersect at their endpoints.
yes polygons are closed figures
For example, figures like C and N are open figures, and figures like O and D are closed.
polygons
Yes quadrilaterals are 4 sided closed figures or polygons
impossible?
