MCQs on Angle Gauges
1 - Question
Which of the following option is incorrect with respect to angle gauges?
a) Sine bar is better than angle gauges
b) Angle gauges are made of high carbon high chromium steel
c) Angle gauges can measure the angle from 0 to 360 degrees
d) They are available in two sets of 13 and 16 gauges
View Answer
Answer: a
Explanation: Angle gauges are more accurate than sine bar as it involves trigonometric functions.
2 - Question

a) 27’+9’-3’+1’
b) 26’+10’-2’
c) 27’+10’-3’
d) 27’+8’
View Answer
Answer: a
Explanation: Combinations can be made by only three series of angle gauges. Minutes series is with 1’, 3’, 9’, 27’ angle gauges.
3 - Question
