What are the properties of the angles?

What are the properties of the angles?

The angle properties of lines are:

  • Vertically opposite angles are equal, for example a = d, b = c.
  • Adjacent angles add to 180o, for example a + b = 180o, a + c = 180.
  • Corresponding angles are equal, for example a = e, b = f, c = g, d= h.
  • Interior angles add to 180o, for example c + e = 180o, d + f = 180.

What are the types of angles in maths?

There are seven types of Angles commonly used in Mathematics:

  • Zero Angle (0° in Measure)
  • Acute Angle (0 to 90° in Measure)
  • Right Angle (90° in Measure)
  • Obtuse Angle (90 to 180° in Measure)
  • Straight Angle (180° in Measure)
  • Reflex Angle (180 to 360° in Measure)
  • Complete Angle (360° in Measure)

How many types of angles are there in mathematics?


Angle Type Angle measure
Right angle 90°
Obtuse angle Greater than 90°, less than 180°
Straight angle 180°
Reflex angle Greater than 180°, less than 360°

What are the 5 angle rules?

What is an angles worksheet?

Angles are an interesting, easy and yet an important topic in Geometry. Angles worksheets show you the easiest method to name angles, understand the types of angles, measure them, concepts of complementary and supplementary angles, and all about linear pairs of angle and transversal angles.

What are the different types of angles in geometry?

Pairs of angles worksheets contain complementary and supplementary angles, linear pair, vertical angles, angles in a straight line, angles around a point, adjacent angles and more. There are seven types of angle pairs formed by a transversal, including corresponding angles, alternate and same side (consecutive) angles.

How to learn angles?

The angles worksheets are the best way to build a strong foundation on the topic of angles. It is always good practice to use visuals while learning any topic. As the worksheets are interactive and provide several visual simulations, they aid a student in his journey to understand the topic.

How do you measure angles in math?

Measuring angles in clockwise and anticlockwise direction using a protractor (mathematical tool) is the main skill emphasized here for grade 5 and 6 students. In the next page, the procedures to measure angles in both ways are shown.
