More than one sided
A polygon is a plane shape with straight sides.
Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is “closed” (all the lines connect up and it does not have any curved lines either).
A regular polygon has all angles equal and all sides equal; otherwise, it is an irregular polygon.
We know some of the most common polygons: those with three sides are triangles, four-sided polygons are quadrilaterals, five-sided are pentagons, six-sided are hexagons and so on.
A shape can have any number of sides, even more than 10 (decagon), and they all have names. Play this memory game to see if you can match these polygons (which have well over 10 sides) with their corresponding number of sides.
