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.

What is an angle? Many people think that an angle is some kind of slanted line. But in geometry an angle is made up of two rays that have the same beginning point. That point is called the vertex and the two rays are called the sides of the angle. To name an angle, we use three points, listing the vertex in the middle.

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.

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.

It's essentially a section of a line that has a beginning and an end. A line continues on forever in both directions, but a line segment starts at one point and ends at a second point. The two points that mark the ends of a line segment are called endpoints. We use the two endpoints to name a line segment and draw a bar (without arrows) on the.

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 $$360^{circ}$$.

Sum of angles on one side of a straight line. The sum of all the angles on one side of a straight line is always 180 degrees. For example, The sum of ∠1, ∠2, and ∠3 is 180 degrees.

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.

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

In the figure, a transversal l is intersecting two lines at point P and Q. Types of Angles. Angles are basically classified as: Acute Angle(<90°) Right Angle(=90°) Obtuse Angle(>90°) Straight Angle(=180°) And based on the relation between two angles, conceptual wise, they are; Supplementary 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°.
