Today we are going to learn five great facts about polygons. number one polygons can be either regular or regular all sides and angles are congruent on a regular polygon. Whereas a regular polygons have two or more sides or angles that are different congruent means that all signs and angles on a regular polygon or identical an example of regular polygon is an equilateral triangle or quadrilateral an example of an irregular polygon. It’s a scaling triangle or a rectangle fact number two any close to the shape three or more sides is considered a polygon a polygon has straight sides not curved.
There are two types of polygons convex and concave a convex polygon. There’s no angles pointing inwards every interior angle of a convex polygon is less than 180 degrees an example of a convex polygon is a signpost or a kite a concave polygon is the opposite of a convex polygon a concave polygon has one or more internal angles greater than 180 degrees one or more of a concave polygons interior angles point inwards an example of a concave polygon is a star or a cross. To number three a complex polygon is a polygon whose side crossover each other one or more times a complex polygon is also known as a self-intersecting polygon an example of a complex polygon would be a star polygon or a pentagram.
The opposite is a simple polygon, which is only one boundary and size do not cross over each other. To number four a polygon’s name will reflect how many sides it has depending on how many sides of polygon has the name of a polygon will change the most commonly known polygons are five-sided which is known as a pentagon a six-sided polygon. It’s called a hexagon a seven-sided polygon is known as a heptagon and finally an eight-sided polygon is called an octagon. regular polygons have rotational symmetry rotational symmetry is when a shape still looks the same no matter how many times you rotate it.
For example, if you were to rotate a square equal lateral triangle or octagon, they will all look the same no matter what side you turn it on regular polygons are also symmetrical and some have more than one line of symmetry. This means that if you were to folder shape in half two sides would match perfectly. I hope you enjoyed my five great facts about polygons. See you soon.
