Help your students prepare for their Maths GCSE with this free complementary and supplementary angles worksheet of 30+ questions and answers
Complementary angles are pairs of angles which sum to 90° (a right angle). Supplementary angles are pairs of angles which sum to 180° (a straight angle). Examples of this include the angles on a straight line and co-interior angles.
Complementary and supplementary angle facts can be used to find missing angles. For example if we have a linear pair of angles, two angles on a straight line, we can find the size of one angle given the size of the other. To do this we subtract the given angle from 180°.
Angle problems often involve knowledge of various types of angles as well as various angle relationships to find an unknown angle.
Looking forward, students can then progress to additional angles rules worksheets and other geometry worksheets, for example an angles in polygons worksheet or volume and surface area of spheres worksheet.
There will be students in your class who require individual attention to help them succeed in their maths GCSEs. In a class of 30, it’s not always easy to provide.
Help your students feel confident with exam-style questions and the strategies they’ll need to answer them correctly with our dedicated GCSE maths revision programme.
Lessons are selected to provide support where each student needs it most, and specially-trained GCSE maths tutors adapt the pitch and pace of each lesson. This ensures a personalised revision programme that raises grades and boosts confidence.
