Trigonális

Trigonális is a term that can refer to several concepts, primarily in mathematics and botany. In geometry, a trigonális or trigonal shape describes something that has three angles or three corners. This is most commonly associated with a triangle, which is a polygon with three edges and three vertices. The term can also be used to describe crystals that exhibit a trigonal crystal system, characterized by a three-fold rotational symmetry axis.

In botany, trigonális is often used to describe the shape of plant parts, such as leaves, stems, or seeds. A trigonális leaf, for instance, might have a triangular outline or three distinct lobes. Similarly, a trigonális stem would have a cross-section that is triangular. This descriptive term helps botanists classify and identify different plant species based on their morphological characteristics. The precise meaning within botany can vary depending on the specific plant group and the part being described, but the underlying concept of three-part symmetry or structure remains consistent.
