Introduction<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading has-large-font-size\"><strong>A. Definition of a Line<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-large-font-size\">A line is a straight, continuous path that extends infinitely in both directions.<\/li>\n\n\n\n<li class=\"has-large-font-size\">It is represented by a straight line with arrowheads on both ends.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading has-large-font-size\"><strong>B. Importance of Lines<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-large-font-size\">Lines are fundamental in geometry and have various applications in real-world scenarios.<\/li>\n\n\n\n<li class=\"has-large-font-size\">They are used to represent paths, boundaries, and relationships in mathematical and scientific contexts.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading has-large-font-size\"><strong>II.

Characteristics<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li>Unlike lines, line segments have a defined length.<\/li>\n\n\n\n<li>They are represented by a portion of a line between two distinct points.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading has-large-font-size\"><strong>C. Examples<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li>Illustrate examples of line segments in everyday situations.<\/li>\n\n\n\n<li>e.g., a piece of string, a segment of a road, etc.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading has-large-font-size\"><strong>III. Half Lines (Rays)<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading has-large-font-size\"><strong>A. Definition<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li>A half line, also known as a ray, is a part of a line that has one endpoint and extends infinitely in one direction.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading has-large-font-size\"><strong>B. Characteristics<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li>Rays have no endpoint in the direction they extend.<\/li>\n\n\n\n<li>They are represented with an arrowhead on one end to indicate the direction of infinity.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading has-large-font-size\"><strong>C. Examples<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li>Relate rays to real-life scenarios.<\/li>\n\n\n\n<li>e.g., sunlight extending from the sun, a flashlight beam, etc.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading has-large-font-size\"><strong>IV. Key Concepts<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading has-large-font-size\"><strong>A. Naming Lines and Segments<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li>Lines and line segments can be named using capital letters or by using symbols.<\/li>\n\n\n\n<li>e.g., Line AB or AB, where A and B are endpoints.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"has-text-align-center has-text-color has-large-font-size\" style=\"color:#105000\"><strong>Learn with an example<\/strong><\/p>\n\n\n\n<div class=\"wp-block-group has-background has-large-font-size\" style=\"background-color:#f8ccae\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<div class=\"wp-block-group has-background-background-color has-background\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<p class=\"has-text-color has-link-color wp-elements-ea1102c8e2362c9df9c755467a9a8a5d\" style=\"color:#b00012\"><strong>1) What is this?<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"177\" height=\"121\" src=\"https:\/\/10thclass.deltapublications.in\/wp-content\/uploads\/2023\/11\/image-1.png\" alt=\"\" class=\"wp-image-9912\" style=\"aspect-ratio:1.462809917355372;width:190px;height:auto\"\/><\/figure>\n\n\n\n<ul class=\"wp-block-list\">\n<li>line <\/li>\n\n\n\n<li>line segment <\/li>\n\n\n\n<li>ray<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n<p>Now look at this figure:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"177\" height=\"121\" src=\"https:\/\/10thclass.deltapublications.in\/wp-content\/uploads\/2023\/12\/image-removebg-preview-2023-12-28T143053.851.png\" alt=\"\" class=\"wp-image-10856\" style=\"width:184px;height:auto\"\/><\/figure>\n\n\n\n<p>This is a ray .
