Interesting Facts About Lines and Angles for Class 9

• A one-dimensional figure that extends in both directions without any specifications about its width is called a line.

• Angles are usually measured in degrees and denoted by ∘ (the degree symbol), which is a measuring representative of rotation and movement.

• There are 5 types of lines :

• Horizontal lines _____

• Vertical lines |

• Perpendicular lines +

• Parallel lines \\

• An angle is the value between 0∘ and 360∘ and is denoted by the ∠  sign.     

• There are 6 types of angles. They are :

• Acute angles - a measure of an angle being less than 90∘ 

• Obtuse angles - the measure of an angles being more than 90∘  but less than 180∘ 

• Right angles - the measure of an angle is exactly 90∘ 

• Straight angles - the measure of an angle is exactly 180∘ 

• Reflex angles - the measure of an angle being more than 180∘  but less than 360∘ 

• Complete angles - the measure of an angle being exactly 360∘ 

• Lines are a set of infinitive number of points that are close to each other.

• The point at which an angle is formed is called the vertex, and the two lines that intersect to create an angle are called its arms (sides).
