*Angles *

An angle measures how far something has turned and it is measured in **degrees**, which are symbolised with a little ^{o} sign after the number. We can measure angles using an object called a **protractor**.

A full turn (coming back to the where you started from) is **360 ^{o}** is

**90**

^{o}A **right angle** is **90 ^{o}** and is one quarter of a full turn.

An angle which is less than a **right angle** (less than **90 ^{0 }**) is called an

**acute angle.**

An angle which is more than a right angle but less than a straight line (more than **90 ^{o }** but less than

**180**) is called an

^{o}**obtuse angle.**

An angle which is greater than **180 ^{o }**is called a

**reflex angle.**

All of the angles inside a triangle will always add up to **180 ^{o}**.

**1) Complete the table**

**2) Look at the angle. Tick the statements that are correct.**

The angle is acute .

The angle is greater than 90°.

The angle is reflex .

The angle is obtuse.

**3) Here is a mosaic**

a) Work out the size of angle is?

b) What type of triangle is in the mosaic?

Isosceles equilateral right angle scalene

**4) Here is a triangle. Without measuring the angle, How can we tell that angle x is 18°.Explain your answer .**
