Angles on a Straight Line WORKSHEET

This worksheet focuses on mastering angles at a point on a straight line, progressing from foundational calculations to advanced problem-solving.

In Section A students 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 but 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 with a line segment is straight using the size of 3 angles, and more.
