Identifying Angles Formed by Parallel Lines & Transverals Worksheet 1 - This angle worksheet features 6 different problems where parallel lines are intersected by a transveral. Consecutive Angles Are SupplementaryGeometryConsecutive AnglesExterior AnglesInterior Angles TERMS IN THIS SET (9) If the two lines are parallel then the alternate exterior angles are congruent. Segments meet at endpoints. If one angle is 90 degrees, then all other angles are also 90 degrees. The angles can be described as interior or exterior depending on where they are located. The consecutive and exterior angle theorem states that if the transversal passes through the two parallel lines then any two exterior angles … consective interrior angles and parallel lines? You can use acute to indicate that an … The 2 angles in purple (d and e) make one pair of consecutive interior angles, and the other 2 angles in red (c and f) make another pair of consecutive interior angles. If parallel lines are cut by a transversal line, then consecutive exterior angles are supplementary. On the other hand two consecutive angles can have any measure not always 180 degrees.
