What is a closed plane figure with at least three sides?

Polygon. A closed plane figure with at least threesides that are segments. The sides intersect only attheir endpoints and no two adjacent sides are collinear. Thevertices of the polygon are the endpoints of thesides.

Also asked, what is a closed figure with three or more sides?

A simple, closed plane figure formed bythree or more line segments meeting only at their endpointsis called a polygon. Polygons are named according to the number ofsides. A regular polygon has all sides congruent andall angles congruent. The vertex of a polygon is where thesides meet.

Also, what are open and closed figures? An open shape is made up of line segments, butthere is at least one line segment that isn't connected to anythingat one of its endpoints. If a shape is enclosed from all the sidesend-to-end and form a figure with no openings is called aclosed shape.

How do you classify a quadrilateral?

Quadrilaterals: Classification

1. A quadrilateral is a polygon with four sides.
2. A rectangle is a parallelogram with four right angles, so allrectangles are also parallelograms and quadrilaterals.
3. A rhombus is a parallelogram with four congruent sides.
4. A trapezoid is a quadrilateral with exactly one pair ofparallel sides.

What is another term for line segment?

Line segments are commonly named in two ways: Bythe endpoints. In the figure above, the line segment wouldbe called PQ because it links the two points P and Q. Recall thatpoints are usually labelled with single upper-case (capital)letters.

Is a circle a closed plane figure?

What is it called when two or more lengths between endpoints of a polygon are the same?

A simple, closed figure formed by three ormore line segments meeting only at their endpoints iscalled a polygon. A regular polygon has allsides and all angles congruent. The vertex of a polygon is apoint common to two sides of the polygon. Figuresthat are the same size and shape are congruent.

How many sides does a polygon have?

A polygon is any 2-dimensional shape formed withstraight lines. Triangles, quadrilaterals, pentagons, and hexagonsare all examples of polygons. The name tells you how many sides theshape has. For example, a triangle has three sides, and aquadrilateral has four sides.
