Description

This image shows two triangles: one regular and one irregular. A triangle is a three-sided polygon. In a regular triangle, also known as an equilateral triangle, all sides and angles are equal, with each interior angle measuring 60 degrees. This regularity gives it a symmetrical and balanced appearance.

An irregular triangle, however, has sides and angles that are not all equal. This asymmetry allows the triangle to take on various shapes, depending on the specific lengths and angles of its sides.
