Angles Starters:Air Traffic Control: Work out which aircraft are in danger of colliding from their positions and direction of travel. An exercise in understanding bearings. Angle Estimates: Estimate the sizes of each of the angles then add your estimates together. Pie Chart: An exercise in estimating what the sectors of a pie chart represent. Sectors: Work out which sectors fit together to make complete circles. Knowledge of the sum of the angles at a point will help find more than one correct solution to this puzzle. Square Angles: Find a trapezium, a triangle and a quadrilateral where all of the angles are square numbers.
