A polygon is a plane figure which comprises one area bounded by three or more straight line segments. A general plane figure can have curved boundaries or sides that cross each other.
intersecting lines...
Perpendicular Lines are two straight lines that intersect to form a 90 degrees or an right angle.Regards,
A trapezium is a plane figure, bounded by four straight lines. One pair of these lines is parallel, the other pair is not.
If none of the sides ever cross each other, there cannot be a closed plane figure.

They are closed plane figures bounded by straight lines that do not cross each other.
A polygon.
All sides are connected with no open gaps, sides do not intersect or cross over each other.

A trapezium (as it is known in English) is a quadrilateral which is a closed plane figure with four straight sides. It has one pair of parallel sides. The other pair of sides is not parallel (otherwise the figure would become a parallelogram).

All 2-dimensional shapes. They may be closed or open, concave or convex, made of straight lines or curved ones, the lines may or may not cross each other.
Sitting meditation is generally done in an upright seated position, either in a chair or cross-legged on a cushion on the floor. The spine is straight yet relaxed. Sometimes the eyes are closed. Other times the eyes are open.
