Question

Which tools were used by ancient mathematicians to make geometric constructions?

compasses and straightedges

protractors and metric rulers

compasses and protractors

protractors and straightedges

Answer 1

The tools that were used by ancient mathematicians to make geometric constructions are compasses and straightedges. A compass is a drawing instrument used to draw circles and arcs. The straightedges on the other hand is a tool to check on the accuracy of a straight line.

The answer is first choice.

Answer 2

Answer:

Compasses and straightedges.

Step-by-step explanation:

• The tool used by the ancient "Greek" mathematician to make geometric construction was the compasses and straightedges.

• The compasses and straightedges can be used to combine to transfer the segment of the given length onto a line.

• This can be done by only the following two steps:

1. Put point A and open it, till mark is visible on point B.
2. Liftoff and put the point on C and mark it on point D till its visible.

• The compasses and straightedges are used to trace the part of the triangle.
