This worksheet focuses on mastering angles at a point on a straight line, progressing from foundational calculations to advanced problem-solving.
In Section A pupils will use bar models to aid them in calculating missing angles.
Next, in Section B learners will decide whether highlighted angles do sum to 180° or not.
Section C sees students calculating more missing angles without the support of a bar model.
Challenge learners with Section D. Here they will solve problems such as forming and solving equations in order to find the size of missing angles, deciding which line segment is straight using the size of 3 angles, and more.
