Describing a shape or structure that has four sides or angles, typically with specific properties in geometry.
The crystal structure of the mineral is tetragonal, meaning it has four equal sides and right angles.
Tetragonal → It is formed from "tetra-" (from Greek "tetras", meaning four) and "gonia" (from Greek "gonia", meaning angle). The word "tetragonal" refers to a shape or structure that has four angles or is related to a four-sided figure.
Think of 'four' ('tetra-') angles ('gonia') to remember that 'tetragonal' describes something with four angles.
