Trigonal planar geometry is a molecular geometry model with one atom at the center and three atoms at the corners of an equilateral triangle, all in the same plane. This arrangement occurs when there are no lone pairs on the central atom, resulting in bond angles of 120 degrees, typically seen in molecules with sp2 hybridization.

An equilateral triangle is a polygon with three equal sides and three equal angles, each measuring 60 degrees. It is a fundamental shape in geometry that exhibits perfect symmetry and is both a special case of an isosceles triangle and a regular polygon.
