BSABE 1-1- CQuiz(Angles and Direction)

The direction of a line is usually defined by the horizontal angle it makes with a fixed reference line or direction

• TRUE

• FALSE

Magnetic meridian can be established by setting up the compass over any convenient point and then sighting a distant object that marks another point on the meridian

• TRUE

• FALSE

The hour hand is pointed toward the sun to determine the true south in the temperate zone.

• TRUE

• FALSE

Azimuth is the acute horizontal angle between the reference meridian and the line

• TRUE

• FALSE

If the forward azimuth of the line is greater than 180 degrees, subtract 180 degrees to obtain the back azimuth.

• TRUE

• FALSE

A close traverse is generally avoided since they offer no way of checking the field measurements for errors and mistakes

• TRUE

• FALSE

In adjusting compass traverse, any station the angle between the forward and back lines can be computed from the observed bearings taken from the station regardless of whether or not the needle is affected

• TRUE

• FALSE

It is an arbitrary chosen fixed line of reference which is taken for convenience and is usually the direction form a survey.
