Recall from the first section, Fundamental Geometry Concepts, that polygons are flat, enclosed 2D shapes with straight sides. At least three sides are needed to create a polygon. You probably already know what a triangle is, but a triangle is formally defined as a polygon with three sides and three angles. “Tri” means three and […]

In this section, we’ll be discussing the properties of parallel lines and transversals. Parallel Lines Parallel lines are lines on the same plane that never intersect. They run side by side at the same distance, infinitely, forever, without meeting. Parallel lines are indicated by drawing an arrow mark on each parallel line. In linear algebra, […]

Learn all about angles and their properties as it relates to geometry. 2.1: Define Angles The space between the rays of an angle is the interior of the angle, the surrounding space is the exterior. Angles can be measured on paper using a protractor. There are many types of protractors with varying levels of accuracy. […]

This article covers all the basics of geometry, including points, lines, segments, rays, planes, and angles. You’ll also learn a bit about postulates, theorems, and proofs. The primary focus is on lines and related geometric figures.  Geometry is the mathematical study of the properties and relations of points, lines, angles, surfaces, and solids. Essentially, it’s the […]
