Alternate and Corresponding Angles WORKSHEET

Suitable for Grades: 8th Grade
CCSS: 8.G.A.5
CCSS Description: Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles. For example, arrange three copies of the same triangle so that the sum of the three angles appears to form a line, and give an argument in terms of transversals why this is so.

Alternate and Corresponding Angles WORKSHEET DESCRIPTION

Spotting corresponding and alternate angles on parallel lines can be tricky for many students. This stripped back worksheet focuses on identifying corresponding and alternate angles rather than calculating missing angles.

Sections A and B consist of the same five diagrams of pairs of parallel lines and a transversal. On each diagram, students will identify one pair of corresponding or alternate angles in section A and B respectively. Answers may vary here, providing a good opportunity for discussion with your student or class.

In section C, a diagram is made up of five parallel lines and two transversals with each angle labeled with a letter. Students will list pairs of corresponding and alternate angles from this diagram, meaning students have to look at the same angles from multiple perspectives and ensure they do not confuse angles on transversals with angles on parallel lines.
