Angles, parallel lines and triangles: key theorems

1. 1If a ray stands on a line, then the sum of two adjacent angles so
   formed is

   1. A100°.
   2. B120°.
   3. C180°.
   4. D360°.
2. 2When the sum of two adjacent angles is 180°, then they are called

   1. Aa vertically opposite pair of angles.
   2. Ba linear pair of angles.
   3. Ca complementary pair of angles.
