Learn Class 5 Math - Angles

Apart from an arithmetical portion of maths, the geometrical portion also plays an efficient role for the class 5 students. This further helps to improve the students' skills.

In Geometry, Angles are very important to let the students completely understand the basics of Geometry. Therefore, here you will get the detailed knowledge of Angles.

Angles

Angles mean any two rays that follow a common endpoint. When we combine it, it forms an angle. It is usually measured in degrees. Angles are classified into two segments: "Sides" and "Vertex".

Angles are like the backbone of Geometry in mathematics. After getting knowledge of Geometry fundamentals, you can easily form complex Geometrical shapes and figures.

Parts of Angles

There are some parts of angles. Some of its parts are as follows:

Vertex: Vertex is a part of the point where arms meet.

Arms: Arms are another part of angles. It comprises two straight-line segments that form a vertex.

Angle: If a ray moves from its endpoint, then the rotation movement is remembered as the angle among its final and initial position.

Classification of Angles

Angles are classified into two types:

  • Based on Magnitude
  • Based on Rotation

Six Types of Angles

In Geometry, there are six main types of Angles depending on their direction. Some of them are noted below:

  • Acute Angles
  • Obtuse Angles
  • Right Angles
  • Straight Angles
  • Reflex Angles
  • Full Rotation
