Understanding angles (age 11+)

Apply the properties of angles at a point (360°), on a straight line (180°), and vertically opposite angles to find unknown angles in multi-step problems

Try this together

If your child is given a diagram with several angles marked at crossing lines and some unknown, can they use the rules about straight lines and crossing lines to find all the missing angles step by step?
