What shape has 5 equal sides and 5 corners?
a regular star
What polygon is a regular star?
A 'concave decagon' is a ten-sided shape with every other corner pushed in towards the centre. It forms a regular five-pointed star.
Is a star a regular poligon?
No, a star is not a regular polygon. A regular polygon has equal-length sides and equal angles, while a star typically has points that extend outward, creating a more complex shape. Stars can be considered star polygons, which have specific rules for constructing their points, but they do not meet the criteria of being regular polygons.
What 2d shape has 5 sides all equal angles and no lines of symmetry?
There is no such shape. A 2d shape with 5 sides and all equal angles must be a regular pentagon (or a 5-pointed star if you stretch the definition of "all angles"). And a regular pentagon - or star - has 5 lines of symmetry.
What was the shape of the stars in the first US flag?
The same as they are now: a regular five-pointed star.
Is a star shape an irregular polygon?
Not all are. Not only is it a concave shape, but the interior angles can vary. For a polygon to be regular, it must be equilateral and equiangular.
What is the mathematical name given to the plain shape traced by the boundary of a regular 5 pointed star?
concave decagon
How many vertices does a stAR HAVE?
A star is not a specific shape: it is a generic word for a shape which has an even number of vertices. The interior angles at alternate vertices are usually reflex angles. A star can have six or more vertices.
Why is star a regular polygon?
A star is considered a regular polygon when its points are evenly spaced and its sides are of equal length. Specifically, a regular star polygon is formed by connecting non-adjacent vertices of a regular polygon (like a triangle, square, etc.) in a consistent pattern. The symmetry and equal angles between the lines connecting these vertices maintain the regularity of the shape. Thus, the defining characteristics of equal sides and angles classify a star as a regular polygon.
What shape have 5 lines of symmetry?
A regular pentagon if your talking external walls, internal lines is a 5 pointed star.
