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.

Pupils are given clues for finding missing angles with this version. Clues include angles within parallel lines highlighted on diagrams, reminders to find base angles in isosceles triangles and more.

Students are required to state reasons alongside each angle calculation throughout. This write-on worksheet has ample space for pupil calculations and answers including reasons.
