## What is an angle KS2 BBC Bitesize?

An angle is a measure of a turn, measured in degrees or °. There are 360° in a full turn. You can find out the size of an angle using a protractor. An angle less than 90° is acute. An angle between 90° and 180° is obtuse.

## What are the 6 different types of angles?

How to measure Different Types of Angles?

• Acute Angle. An angle which measures less than 90° is called an acute angle.
• Right Angle. An angle which measures exactly 90° is called a right angle.
• Obtuse Angle.
• Straight Angle.
• Reflex Angle.
• Complementary & Supplementary Angles.

What are the rules of 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.

How do you describe an angle?

An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’ meaning “corner.”

### What are the 10 types of angles?

Summary

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°
