What is a polygon with 5 vertices?
A pentagon has five straight sides and five vertices (corners). It has five angles inside it that add up to 540°.
What kind of shape has 5 sides?
In geometry, a pentagon (from the Greek πέντε pente meaning five and γωνία gonia meaning angle) is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting. A self-intersecting regular pentagon (or star pentagon) is called a pentagram.
Do all polygons have 5 sides?
More than Four Sides A five-sided shape is called a pentagon. A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides… The names of polygons are derived from the prefixes of ancient Greek numbers.

What is a real life polygon?
Transcript of Polygons in real life. A simple polygon that is not convex is called concave, non-convex or reentrant. A concave polygon will always have an interior angle with a measure that is greater than 180 degrees. A polygon that does not have all sides equal and all angles equal. A plane figure with three straight sides and three angles.
What shape has got 5 sides?
Naming 2D Shapes Using Sides and Corners Triangles have 3 sides and corners. Any 2D shape with three corners or three sides is called a triangle . Quadrilaterals have 4 sides and corners. The 2D shapes below all have four corners and four sides . Pentagons have 5 sides and corners. Hexagons have 6 sides and corners. Circles have no corners.
What are facts about polygon?
A polygon is a plane (2 dimensional) figure that features at least 3 straight sides and angles. A regular polygon has sides which are all the same length as well as angles which are all the same. Examples of regular polygons include the equilateral triangle and square.
