Introduction to angles:
Angle is union of two different rays having the same initial point is called as angle. Thease two rays are called as the arms or the sides of the angle.When the two rays are meeting at the same point is called as vertex of the angle.We can use to denote the angles in three capital letters. More types of angles are available in the geometric basics.Angles are classified based on the inclination. We can measure the angle using Protractor
Protractor
See which scale to use.
when the angle of measurement is < 90 degrees is called an acute angle.
Right angle is also called as vertical angle. The angle of 90 degree object is called right angle.
The angle whose measure is > 90 degrees and < 180 degrees is called obtuse angle.
Straight angle is also called as horizontal angle.Angle is 180 degree
when the measurement of angle is >180 degrees and less than 360 degrees that is called reflex
Angle with a common vertex and one common side is adjacent.
Two angles whose measures add to 180 degrees
An exterior angle is usually measured the angle between the any one side of a triangle and the extension of an adjacent side of the triangle .
When two lines are crossed by the another line the angles in matching the corners such angles are called as the corresponding angles.
it is also used to measure the angle >180^{o} and < the 360^{o} is called a reflex angle
the total angle is 360 which angle covers the total value is called a complete angle.
if the Two angles are said to be equal, then they are called as the equal angle
which Two angles having a common vertex and a common arm, such angles are called as adjacent angle .
