First term Examination 1

Assertion: If an angle formed by two intersecting lines

is 60, then its vertically opposite angle is 60.

Reason: If two lines intersect each other, then the

vertically opposite angle is 60.

• Both assertion and reason are true and the reason is

  the correct explanation of assertion.

• Both assertion and reason are true but the reason is

  not the correct explanation of assertion.

• The assertion is true but the reason is false.

• The assertion is false but the reason is true.

Two lines will meet in one point only when they are

parallel.

• True

• False

If two interior angles on the same side of a transversal intersecting two parallel lines are in the ratio 5 : 4,then the greater of the two angles is

• 54
  

• 100

• 120

• 136

If the supplement of an angle is three times its

complement, then the angle is

• 40

• 35

• 50

• 45

An angle is 14 °more than its complementary angle,

then angle is

• 30

• 52

• 50

• None of these

The rational number between 1/2 and 1/3 is

• 2/5

• 1/5

• 3/5

 $0.12\overline{3}$  can be expressed in rational form as

•  $\frac{900}{111}$  

•  $\frac{111}{900}$  

•  $\frac{123}{10}$  

•  $\frac{121}{900}$
