🌱Only in the lateral views did the X-rays reveal an suspicious-looking shadow on the lung. 🌳Lateral shows up in all kinds of contexts. A lateral job change is one that keeps you at about the same job level and salary. A coach might have special drills to improve his players' lateral speed and agility. The British speak of "lateral thinking," thinking that grabs ideas that may not seem to be relevant but turn out to work well—what we might call "thinking outside the box." But we know lateral best from football. A lateral pass is a pass of the ball between teammates that usually goes to the side and slightly backward from the direction in which they're advancing; unlike a forward pass, a lateral may be made from any position, and any number may be made in a single play. bilateral Involving two groups or countries.

The word is mostly used in geometry. The standard polygons （many-sided geometrical shapes）—the pentagon, hexagon, octagon, etc.—are assumed to be equilateral if we don't say otherwise; an equilateral rectangle has the special name square. But triangles are particularly important, and many triangles are not equal-sided. The standard polyhedrons （many-sided solids are also equilateral. Most common is the cube, all of whose sides are square. The tetrahedron has four triangular sides and thus is a pyramid with a triangular base, unlike the pyramids of Egypt with their square bases.
