SURVEY . a star has 10 sides, decagon A polygon is irregular, if it is not regular. Tags: Question 37 . As well, concavity and convexity do not impact this fact! So, no, a star is actually a REGULAR polygon. Why is a Triangle called Equilateral? It is considered irregular because the angles and sides are not equal. Most people can doodle a star on paper quickly, but few people label it a pentagram , complex polygon, or self-intersecting polygon. answer choices . Q. Key stage 2 regular and irregular shape practice questions The classic star is a complex polygon. They are usually not equal to any other one side. 60 seconds . The five-pointed star on the flag of the United States is actually an irregular decagon, as each of the stars has 10 sides. Irregular polygon. Regular Polygon. The stars are connected with imaginary lines to form shapes or patterns. In Year 6, pupils compare and classify geometric shapes based on their properties and sizes and find unknown angles in any triangles, quadrilaterals, and regular polygons. All stars are concave polygons. So, no, a star is actually a REGULAR polygon. It has four sides that match. It has no sides that match. Star Polygons Definition. Regular Polygon Irregular Polygon . Irregular polygon . In Year 5, pupils distinguish between regular and irregular polygons based on reasoning about equal sides and angles. ... or an irregular polygon. It has all 3 sides that match. Q. This is a type of polygon with all the interior angles strictly less than 180 degrees. The family of complex star-shaped polygons generally share the Greek number prefix and use the suffix -gram: pentagram, hexagram, octagram, and so on. Irregular polygons are polygons that have unequal angles and unequal sides, as opposed to regular polygons which are polygons that have equal sides and equal angles. answer choices .
