A no prep worksheet on angle relationships of angles formed when two lines are cut by a transversal. The following relationships are included:
- Corresponding Angles
- Alternate Interior Angles
- Consecutive Interior Angles
- Vertical Angles
- Supplementary Angles
- Angles in triangle
Twelve challenging problems are included. Students practice finding the value of missing angle measures using the angle relationships seen in parallel lines cut by a transversal to form equations and then solve.
Students will receive three sheets of paper with problems that need to be solved and the teacher will receive detailed solutions for these problems as well.
Master advanced angles in parallel lines and triangles with this GCSE Maths worksheet! Ideal for KS3 and KS4 multi-step geometry revision.
