Angles on a line / at a point

This simple worksheet focuses on using the following 3 rules for working out angles:



1. sum of angles on a straight line = 180

2. sum of angles at a point = 360

3. vertically opposite angles are equal



It begins with brief revision of the names for different sizes of angles and then there is a section for each of the 3 rules. Each section contains some example questions to work through with your class and then there is a short exercise for them to complete.



At the end there is an exercise of mixed questions to practise using all 3 rules. Answers to the exercises are included.



I used this sheet with my (bottom set) year 10 group. The idea was that printing/projecting the sheet would save me (and them) having to write out any examples/diagrams as notes, so that time is saved and they can focus on answering questions. After completing the sheet the class were ready to attempt additional exercises from a textbook.
