The shape of a mirror with 5 sides is called a pentagon. In geometric terms, a pentagon is defined as a five-sided polygon. Each side of the mirror can be of equal length, making it a regular pentagon, or the sides can vary in length, resulting in an irregular pentagon.
Explanation: When we think about shapes, each polygon is named based on the number of its sides. A triangle has 3 sides, a square has 4, and so forth. Therefore, since Josie’s mirror has 5 sides, the correct term to describe its shape is a pentagon. This unique shape can lead to interesting reflections and visual effects, depending on how light interacts with the mirror’s edges.
