Geometry Basics: Points, Lines and AnglesHoover, Elizabeth
lines, angles, surfaces, and solids. In this blog post, we'll be focusing on lines and angles— two of the most basic concepts in geometry. By the end of this post, you should have a good understanding of what lines and angles are, as well as some of the properties that they posses...
Perpendicular lines:When there is a right angle between two lines, the lines are said to be perpendicular to each other. Here, the lines OA and OB are said to be perpendicular to each other. Parallel lines: Here, A and B are two parallel lines, intersected by a line p. The line p ...
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, ...

Lines and Angles are basic shapes in geometry. Definitions of different types of lines and angles along with their properties are explained here at BYJU'S with examples and video lessons.
This video explains and demonstrates the fundamental concepts (undefined terms) of geometry: point, line, plane. Show Step-by-step Solutions Angles When two lines intersect at a point, they form four angles, as indicated below. In the figure, anglessandqare calledopposite angles, also known as...
