Lines (Geometry) Practice Test Question Answers
Two angles are called adjacent angles if they have a common vertex and a common arm but no common interior points. A linear pair is a pair of adjacent angles whose non-common sides are opposite rays. When two lines intersect, the vertically opposite angles so formed are equal.
If two parallel lines are intersected by a transversal, (i) each pair of corresponding angles is equal. (ii) each pair of alternate interior angles is equal. (iii) each pair of interior angles on the same side of the transversal is
supplementary..

Lines (Geometry) Practice Test Question Answers
1. If two lines are intersected by a transversal, then the number of pairs of interior angles on the same side of
the transversal is |
🔘 A. 0 |
🔘 B. 1 |
🔘 C. 2 |
🔘 D. 3 |
🔘 E. 4 |
2. In the given figure, find out which pair of lines are parallel.

|
🔘 A. GH || KP |
🔘 B. EF || KP |
🔘 C. AB || CD |
🔘 D. EF || GH. |
🔘 E. NOTA |

Answer:D. EF || GH. [Solution: For lines EF and GH, taking CD as transversal, ∠1 and ∠2
are interior angles on the same side of the transversal. Therefore, we check whether the sum of ∠1 and ∠2 is 180° or
not. ∠1 = 123°, ∠2 = 57°, ∠1 + ∠2 = 123° + 57° = 180° Since the sum of the interior ∠’s on the same side of the
transversal is 180°, therefore EF || GH.
3. In the following lines, l and m intersect each other at a point. Which of the following is false?

|
🔘 A. ∠a = ∠b |
🔘 B. ∠d = ∠c |
🔘 C. ∠a + ∠d = 180° |
🔘 D. ∠a = ∠d |
🔘 E. NOTA |
Show Answers
Answer:D ∠a = ∠d (Sol ∠a + ∠d = 180°)
4. In the following figure POR is a line. The value of a is

|
🔘 A. 20° |
🔘 B. 40° |
