Do more than solely identify corresponding, alternate, and co-interior angles with this worksheet, as the missing angle calculations increase in difficulty. The worksheet will see learners progress to finding missing angles after up to three steps. Multi-step problems include using vertically opposite angles, angles in triangles and quadrilaterals, angles on a straight line, and base angles in isosceles triangles.

Students are required to state reasons alongside each angle calculation throughout, and we have produced two versions: one with handy clues to get your students going, if necessary.

This write-on worksheet has ample space for student calculations and answers including reasons.
