Answer:
A) Protractor
Step-by-step explanation:
In Mathematics, geometric constructions refers to the drawing of geometric shapes, lines and angles with the exclusive aid of a pencil, straightedge/ruler and a pair of compass.
The pencil is the major drawing tool during the construction while the pair of compass and straightedge are used to construct arcs/circles and straight lines respectively. Note that, a PROTRACTOR is not needed in a geometric construction because length or angle measurements are prohibited.
In true geometric construction, we can not use Protractor.So that, protractor is not tool for geometric construction.
Option a is correct.
The two tools that we need to make geometric constructions are these two: compass, straightedge.
By using compass , to make various arcs from different points, these arcs will intersect at important points that we can then use the straightedge to connect with other points.
Measurements using a protractor or a ruler is never considered to be part of a geometric construction.
