When two or more lines cross or meet each other in a plane, the lines are called intersecting lines. 1. Point of Intersection: Intersecting lines share a common point called the point of intersection. In the figure below, lines p and q intersect at point O. So, point O is the point of intersection. In the image below, many straight lines cross each...
Intersecting lines refer to two or more lines that cross or meet at a common point, which is known as the point of intersection.
Scissors: The two arms of a pair of scissorsCrossroads: Two roads (considered straight lines) meeting at a common point make crossroads.Patterns: The lines on the floorWhen two lines intersect each other, different types of anglesare formed. The angles formed by the intersection of two lines are vertical angles, adjacent angles, linear pairs of angles. 1. Adjacent Angles (Bold) Adjacent angles are the anglesthat share a common vertex and a common side. In the figure given below, the pair of adjacent angles is: (i...
Parallel linesare a pair of lines that never intersect and remain equidistant from each other at all points. In the figure given above, lines a and b are parallel lines. They never meet and the perpendicular distance between them is always the same.
In this article, we learnt about intersecting lines, angles formed by them, parallel lines, and the point of intersection. Let’s solve a few examples and practice problems based on intersecting lines!
1. Answer the following questions based on the information given in the diagram. (a) Lines GH↔and CD↔ are _____ lines. (b) Lines EF↔ and CD↔are _____ lines. (c) Which line segments are intersecting? Give one example. Solution: (a) GH↔ and CD↔intersect each other at one point, which is Q. So, they are intersecting lines. (b) Lines EF↔ and CD↔ do not...
Sep 5, 2021 · \(\overleftrightarrow{AB} || \overleftrightarrow{CD}\) since the arrows indicate parallel lines. \(x^{\circ} = 40^{\circ}\) because alternate interior angles of parallel lines are equal. \(y^{\circ} = z^{\circ} = 180^{\circ} - 40^{\circ} = 140^{\circ}\). Answer: \(x = 40, y = 140, z = 140\).
Intersecting lines can form four types of angles: right (90°), acute (less than 90°), obtuse (more than 90°) and straight (180°). The type of angle formed depends on the angle at which the two lines meet. For example, two perpendicular lines will form a right angle (90°).
