Which term describes two polygons that have the same shape but not necessarily the same size?

The term that describes two polygons with the same shape but not necessarily the same size is ‘similar polygons.’ Similar polygons have corresponding angles that are equal and the lengths of corresponding sides are proportional. This means that while the overall form and angles are identical, the two shapes can vary in size, maintaining their geometric properties.

Understanding similar polygons is important because it allows you to analyze geometric relationships where size may change but shape remains constant, such as in scaling diagrams or maps. In contrast, congruent polygons would need to be exactly the same in size and shape, while regular polygons refer to those with equal side lengths and angles, and composite polygons are shapes formed by combining two or more polygons.
