Types of angle
In geometry, there are various types of angles, based on measurement. The names of basic angles are Acute angle, Obtuse angle, Right angle, Straight angle, reflex angle and full rotation. An angle is geometrical shape formed by joining two rays at their end-points. An angle is usually measured in degrees.
There are various types of angles in geometry. Angles form the core part of the geometry in mathematics. They are the fundamentals that eventually lead to the formation of the more complex geometrical figures and shapes.
What are Angles
When two rays combine with a common endpoint and the angle is formed. The two components of an angle are “sides” and “vertex”. The side can be categorized into terminal sides and initial sides (or vertical sides) as shown in the image below.
Representation of an Angle
These two rays can combine in multiple fashions to form the different types of angles in mathematics. Let us begin by studying these different types of angles in geometry.
Parts of Angle
Vertex – Point where the arms meet.
Arms – Two straight line segments form a vertex.
Angle – If a ray is rotated about its endpoint, the measure of its rotation is called angle between its initial and final position.
Answer:
The different types of angles based on their measurements are: Acute Angle - An angle less than 90 degrees. Right Angle - An angle that is exactly 90 degrees.
Angle Type Angle measure
Acute angle Greater than 0 °, Less than 90°
Right angle 90°
Obtuse angle Greater than 90°, less than 180°
Straight angle 180°
