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?

| Acute angle | Greater than 0 °, Less than 90° |
| Right angle | 90° |
