math terms

Polygon
One of the first things children learn about in school is the concept of shapes, and that’s what a polygon is — a figure with at least three straight sides and three angles. Simple polygons include triangles, squares, pentagons, and even stars. However, shapes such as circles, hearts, and moons are not polygons, because they have curves. The word comes from the Greek term polugōnos, meaning “many-angled.”

Quadratic equation
A quadratic equation involves unknown variables with an exponent no higher than the second power. See the image below. Striking fear into the hearts of many, this equation is important because solving it unlocks a world of mathematical power. The basic formula is used across almost every field of engineering, science, and business. The name comes from the Latin word quadraticus, meaning “made square.”
