Chapter 2 - Section 2.1 - The Parallel Postulate and Special Angles - Exercises - Page 74: 3b



Work Step by Step

If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent. Since we are given that lines l and m are parallel, and $\angle$2 and $\angle$6 are corresponding angles, we know that $\angle$2 and $\angle$6 are congruent. Since $\angle$2=68.3$^{\circ}$, $\angle$6 must also be 68.3$^{\circ}$.
