Which segment is parallel to BE ? F AB H CF G BC J DF 3. Which segment is NOT skew to DF ? A 1 and 8 are supplementary. B 4 and 8 are supplementary. A AB C BC C 3 and 7 are congruent. B AC D BE D 7 and 8 are congruent. Refer to the figure for Exercises 4 and 5. 8. Why is m n? F If two coplanar lines are perpendicular to the same line, then the two lines are parallel to each other. 4. Which pair of angles are corresponding angles? F 1 and 4 H 2 and 5 G 6 and 8 J 8 and 7 5. Which pair of angles are alternate exterior angles? A 4 and 8 C 3 and 7 B 2 and 5 D 1 and 4 G If two parallel lines are cut by a transversal, then the pairs of sameside interior angles are supplementary. H In a plane, if a transversal is perpendicular to one of two parallel lines, then it is perpendicular to the other line. J If two intersecting lines form a linear pair of congruent angles, then the lines are perpendicular. Original content Copyright © by Holt McDougal.
