 # Lines and Angles – Definitions & Properties (Geometry Tutorial)

Ancient mathematicians introduced the concept of lines to represent straight objects which had negligible width and depth. Considered as a breadth less length by Euclid, lines form the basis of Euclidean geometry. When two rays(part of a straight line) intersect each other in the same plane, they form an angle. The point of intersection is

In this article, we are going to learn about the simplest form of a polygon, a triangle. All polygons can be divided into triangles, or in other words, they are formed by combining two or more triangles. Thus, understanding the basic properties of triangles and their types is important. Here is an outline of the

Read More  Quadrilateral questions have always been a head-scratcher for a lot of candidates taking competitive or standardized exams. The primary reason behind it is learning a concept is easier as compared to applying that concept to solve questions. Therefore, to help you with the application of properties of quadrilaterals we have shared a few quadrilateral questions

In Euclidean geometry, a quadrilateral is a four-sided 2D figure whose sum of internal angles is 360°. The word quadrilateral is derived from two Latin words ‘quadri’ and ‘latus’ meaning four and side respectively. Therefore, identifying the properties of quadrilaterals is important when trying to distinguish them from other polygons. So, what are the properties

A circle is a closed shape formed by tracing a point that moves in a plane such that its distance from a given point is constant. The word circle is derived from the Greek word kirkos, meaning hoop or ring. in this article, we cover the important terms related to circles, their properties, and various
