Irregular vs Regular Pentagon: Geometry Comparison Guide #3381583 (License: Personal Use)

The image displays two black-outline pentagons on a white background for direct visual comparison. The left shape is an irregular pentagon-its sides and interior angles differ, breaking rotational and reflectional symmetry. The right shape is a regular pentagon, featuring five congruent sides and five equal interior angles (each 108°), exhibiting five lines of symmetry and 72° rotational symmetry.

This image is commonly used in educational math resources, geometry textbooks, or online tutorials to illustrate polygon classification. It supports user intent to understand geometric properties, prepare for exams, or teach foundational concepts in Euclidean geometry.
