More about Ray and Lines
Remember that a part (or part) of a line with two endpoints is called a line segment and a part of a line with one end is called a Ray. Note that AB marks the line segment AB and its length mark AB. AB represents Ray AB, and AB represents a line. However, we will not use these symbols, and we will mark the line segment AB, the beam AB, the length AB and the line AB having the same AB. The doubt will be very clear from the context. Sometimes lowercase letters l, m, n, etc., will be used to indicate the lines.
Collinear and Non-Collinear points
If three or more points are on the same line, they are called collinear points; Otherwise, they are called non-collier points. Remember that an angle is formed when two rays originate from the same end. The rays that make an angle are called the sides of the angle. The endpoint of the joining of the two rays is called the vertex of the angle. You have studied different types of angles in previous classes such as acute angle, right angle, obstetric angle, right angle and reflex angle.

Types of Angles
An acute angle measures between 0° and 90°, while a right angle is equal to 90°. An angle greater than 90° but less than 180° is called an angle. Also, remember that the right angle is equal to 180°. An angle that is greater than 180 ° but less than 360° is called a reflex angle. Also, two angles whose sum is 90° are called complementary angles and two angles whose sum is 180° are called complementary angles. You have also studied the adjacent angles in previous classes. Two angles are adjacent if they have a common vertex, a joint arm and their abnormal sides on different sides of the joint arm.
