Calculating Angles on Parallel Lines with Transversals (B) 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.
Calculating Angles on Parallel Lines with Transversals (B) WORKSHEET DESCRIPTION
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.
