Here, we are going to discuss the intersecting lines. Intersecting lines are the two lines that intersect each other at a point. One of the properties of angles is: the sum of the angles at one side of a straight line are always equal to $$108^{circ}$$, whereas the sum of the angle around a given point is always equal to the $$360^{circ}$$.

Angles on a Straight Line/Around a Point Worksheet Teaching Resources
Lines and angles are basic terms in geometry. A line is a straight path between two points, while an angle is the figure formed by two lines that meet at a point. Angles are measured in degrees, with a full circle being 360 degrees. Lines and angles are important concepts in geometry because they can be used to describe the shapes of objects.

Basic math angle facts; angles in a triangle, on a straight line and around a point.
Perpendicular Lines. Perpendicular lines () are two lines that intersect to form right angles. Recall that a right angle measures 90 . This figure is very important not only in geometry, but in science and engineering. Graphs in either two or three dimensions have axes at right angles to each other. Gravity acts perpendicularly to the horizontal.

1.2: Angles An angle is the figure formed by two rays with a common end point, The two rays are called the sides of the angle and the common end point is called the vertex of the angle. 1.3: Angle Classifications; 1.4: Parallel Lines Two lines are parallel if they do not meet, no matter how far they are extended. 1.5: Triangles
G3a Angles at a point, angles at a point on a straight line, vertically opposite angles
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. Figure 9.1. 5: Examples of Angles.

One of the properties of lines and angles states that the sum of the adjacent linear angles formed by a line is 180°. Therefore, 4x + 2x = 180°. 6x = 180°. x = 180°/6 = 30°. We get the value of x as 30°. Hence, the first angle AOB is 4x = 4 × 30 = 120°. The other angle COB is 2x = 2 × 30 = 60°.

An angle is a space or the gap formed between two lines that meet at a point and the meeting point is called the Vertex. The two lines originating from the same point are called the arms of the angle. The Angles are classified into different types such as Acute angle, Right angle, Obtuse angle, Straight angle, Reflex angle, and Full angle.

Relationship between Lines and Angles. We have learnt the basics of angles from its definition, measurement of an angle to its various types of angles. As we have seen that angles are formed only when two lines intersect at some point. So, there are many more case where different types of angles are defined when lines intersect each other.

Line segments. A line segment is a piece of a line that connects two points. The points at the end of the line segment are called endpoints. You name a line segment by using its endpoints. The symbol for a line segment is the letter name of each of the endpoints with a line over the top. A drawing of a line segment has two points at the ends.
