Select one:

c. protractor

Answer 1

Answer: B, plumb bob

Step-by-step explanation:

A plumb bob's main job was to establish what is true (ie vertical and perpendicular to a surface,) as well as the secondary task of marking these points.

Compasses are mainly used to draw circles, protractors are used to measure angles, and rulers are used to measuring length.
