  1. 1. (c) complementary — Angles summing to 90° are complementary.
  2. 2. (d) parallel — Such lines are parallel.
  3. 3. (a) 60° — 180° − 120° = 60°.
  4. 4. (b) equal — They are equal.
  5. 5. Two angles that add up to 180°.
  6. 6. Equal.
  7. 7. When two straight lines cross, four angles are formed at the point of intersection. Any two adjacent angles lie together on a straight line and form a linear pair, so they add up to 180°. The two angles that are directly across from each other — not adjacent — are called vertically opposite angles, and they are always equal to each other. So at a crossing, if one angle is 70°, the angle opposite it is also 70°, while each neighbouring angle is 180° − 70° = 110°. These relationships let us find every angle at the intersection once one is known.
