The capability of showing small angular movements of the level rube vertically, is called its sensitivity.

Right

Wrong

132.

In order to measure a horizontal angle more accurately than a vernier, a

A.	method of repitition is used	B.	method of reiteration is used
C.	method of deflection angles is used	D.	method of double observations is used

133.

in measuring horizontal angles, the theodolite should be turned

A.	clockwise from the forward station to the back station	B.	clockwise from the back station to the forward station
C.	anticlockwise from the forward station to the back station	D.	anticlockwise from the back station to the forward station

134.

The method of reiteration of measuring horizontal angles is generally preferred when several angles are to be measured at a particular station.

Yes

135.

An angle made by a survey line with the prolongation of the proceeding line, is known as

A.	direct angle	B.	vertical angle
C.	horizontal angle	D.	deflection angle

136.

A deflection angle in a traverse is equal to the

A.	difference between the included angle and 180?	B.	difference between 360? and the included angle
C.	sum of the included angle and 180?	D.	none of the above

137.

The deflection angle may have any value between

A.	0? and 45?	B.	0? and 90?
C.	0? and 120?	D.	0? and 180?

138.

An angle measured clockwise from the proceeding survey line to the following survey line is called

A.	direct angle	B.	vertical angle
C.	horizontal angle	D.	deflection angle

139.

The deflection angle may be directly obtained by setting the instrument to read

A.	0?	B.	90?
C.	180?	D.	270?

140.

The direct angles may have any value between

A.	0? and 90?	B.	0? and 120?
C.	0? and 180?	D.	0? and 360?
