Basic math angle facts; angles in a triangle, on a straight line and around a point.
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.
Line Angles Part 1
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.

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.

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.

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.

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

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.

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.
