Calculating Angles B contains most angles facts from KS3 and acts as a perfect recap for KS4 students and as a challenge for KS3 students. The worksheet consists of twenty missing angles to find across twelve diagrams and includes the following rules: angles in a parallelogram, angles in trapezia, angles in triangles including isosceles, angles around a point, angles on a straight line, angles in parallel lines and even images where the parallel lines need to be extended to solve.

We have created two versions of this worksheet. This version includes clues highlighting angles on parallel lines, which angle to find first and more. Decide which is appropriate for your class or for individuals to use.
