There are examples of pentagons in real life in man-made structures like the Pentagon in the United States, and also in nature in flowers like morning glories and okra. Other items, like home plates in baseball, are often in the shape of irregular pentagons.
Know MoreA pentagon is a five-sided shape. If the sides are all the same length, the internal angles will be the same size as well, and the shape is called a regular pentagon. Any other pentagon with sides of varying length is an irregular pentagon. Despite having just one more side than a square, pentagons are used and seen much less frequently in real life.
