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.
The six types of angles are right angle, acute angle, obtuse angle, straight angle, reflex angle, and complete angle. The different types of lines are horizontal lines, vertical lines, parallel lines, perpendicular lines, and transversal lines.
LINES AND ANGLES. 6.1 Introduction. In Chapter 5, you have studied that a minimum of two points are required to draw a line. You have also studied some axioms and, with the help of these axioms, you proved some other statements.
This topic introduces you to basic Geometry, primarily focusing on the properties of the angles formed: i) when two lines intersect each other and ii) when a line intersects two or more parallel lines at distinct points. This chapter falls under the Unit – Geometry and is included in the CBSE Syllabus of Class 9 Maths.
Line. A line is a straight path which has no endpoints. Line Segment. A line segment is a straight path which has two endpoints. Ray. A ray is a line which has one endpoint and endless from another side. Angles. The corners made by the intersection of two lines or line segments are called Angles.
May 26, 2022 · Angles that are between 0º and 90º (smaller than right angles) are called acute angles. Angles that are between 90º and 180º (larger than right angles and less than 180º) are called obtuse angles. And an angle that measures exactly 180º is called a straight angle because it forms a straight line.
