Question 1 of 20

2. Two lines are parallel to each other, only when

 They do not intersect each other when extended on either side

 The lines lie on the same plane

Question 2 of 20

3. The angle whose complement is one-third of its supplement will be

 135°

 90°

 180°

 45°

Question 3 of 20

4. Choose the correct statement

  If angles forming a linear pair are equal, then each of these angles measures 90°.

 Angles forming a linear pair can both be acute angles.

  If two adjacent angles are equal, then each angle measures 90°.

 Two angles whose sum is 90° are called supplementary angles.
