Answer:
Compass, and straightedge/ruler.
Explanation:
The two basic tools for doing geometric constructions are:
Compass: A compass is a drawing tool that consists of two arms, one with a sharp point and the other with a pencil or pen. It is used to draw circles, arcs, and to mark off distances.
Straightedge or Ruler: A straightedge is a tool with a straight, unmarked edge. It is used to draw straight lines, measure lengths, and create parallel or perpendicular lines.
These two tools, the compass and straightedge (or ruler), are fundamental for performing geometric constructions, where precise shapes and figures are created using only these tools and basic geometric principles.
