What can you remember about angle rules?
You might not recall them all, but there are probably some that you already know.
Here are the most important ones to remember:
A right angle is 90º
The angles inside a triangle add up to 180º
The angles around a point add up to 360º
A straight line angle is 180º
These other ones involve remembering some names too!
An acute angle is less than 90º
Easy to remember because 'a cute' kitten is very small!
An obtuse angle is between 90º and 180º
A reflex angle is between 180º and 360º
How many of those did you already know?
Let's have a go at applying some of these rules in the questions that follow.
