Deepen understanding of how to calculate vertically opposite angles by using this resource.

This Year 6 Vertically Opposite Angles Reasoning and Problem Solving worksheet helps children use the knowledge that two lines intersecting will cause vertically opposite equal angles to calculate the value of missing angles. Children will identify and explain an error in calculating vertically opposite angles then reason whether a child has calculated a vertically opposite angle correctly. Finally, they will find possible angles that satisfy a problem. All answers are also included so that marking is as easy as possible!

A varied fluency resource is also available for this small step.
