Ray
A Ray is defined as a line which has fixed starting point but lacks a defined endpoint. A ray can extend infinitely in a singular direction. Due to the absence of an endpoint, measurement the length of a ray is not applicable. For examples, a sunray or the light emitted from a torch, where the sun or the torch serves as the originating point, and the ray extends indefinitely.
Lines in Geometry: Definition, Types and Examples
A Line is a one-dimensional geometric figure that exists only in length without width and thickness. A Line comprises a group of points; it extends infinitely in opposite directions or combines with other lines to form various shapes. In a two-dimensional plane, a line is uniquely defined by a pair of points. Points situated on the same line are termed collinear.
In this article, we will discuss the introduction, definition of Line, and its meaning. We will also understand the different types of Lines and various equations related to Lines. We will also solve various examples and provide practice questions for a better understanding of the concept of this article.
