Lesson: Parallel Lines and Transversals: Angle Relationships Mathematics • First Year of Preparatory School

Students will be able to

• identify and name corresponding, interior, and alternate angles formed by two lines and a transversal,
• state and use the fact that the measures of two alternate angles and two corresponding angles are equal when the two lines are parallel,
• state and use the fact that two interior angles on the same side of the transversal are supplementary,
• identify that two lines are parallel if they are cut by a transversal such that two alternate angles are equal, two corresponding angles are equal, or two interior angles are supplementary.
