In math geometry the lines and angles are important tools. If any object in ideal, that is called as line and it is represented as straight curve. The angle is related with line that is the cross-section of two-line is create the angle and that intersection point is called as vertex. Here we see about types of line and angle in math.
Explanation for lines in math
Lines:
If we want to project the real world model in geometry means we can use the lines for straight object representation. This straight object is represented with small height and width and it is infinitely long. The Euclidean math geometry use the line commonly.
Types of lines:
Parallel lines:
The separate two coplanar lines are called as parallel lines that are this line does not intersect with each other. The distance between the two lines are equal and it is represented as | |. The parallel lines are illustrating the two postulates.
Corresponding angles postulate: The angles are same when the transversal is cut the two coplanar lines. So we can say that lines are parallel.
Parallel lines postulate: If the transversal cut the two parallel lines, the same measure angles are present.
Perpendicular lines:
When the angle of 90 degree on two lines that two lines are said to be as perpendicular lines. This perpendicular line is represented as ‘_’. The perpendicular line does not have any postulates but solve some theorems. They are perpendicular lines and slopes theorem, perpendicular to parallel theorem and two perpendiculars theorem.
Explanation for angles in math
Angles:
The above diagram is illustrating the angle by lines. The vertex of angle is A. The meeting line of two lines is called as arms of the angle and the arm points are used for naming the angle. When one angle arm is moved to the other arm is represent the size of an angle.
In math the degree is used for angle size measurement and in geometry the protractor is used. Adjacent angles, complementary angles ad supplementary angles are pairs of angles.
