The last in our series on angles in parallel lines, this worksheet will challenge KS3 and KS4 students in both foundation and higher tiers. There are twenty missing angles to find across nine diagrams which gets increasingly difficult. Students will have to use a multitude of angle rules to calculate the missing angles, including spotting where to find a missing angle in a triangle and extending parallel lines.
In section B, learners are given three problems where they will have to form and solve equations before calculating the size of each angle.
This version contains clues such as highlighting angles on parallel lines, suggesting an angle to calculate first and how to form an equation in section B. Choose which is appropriate for your class or individuals.
