You are probably referring to a line, ray, or a line segment.
Each of these figures are straight and are one-dimensional (or 1D).
A line goes forever in both directions, and looks like an arrow pointing in 2 opposite directions.
A ray goes forever in one direction. It has an arrow pointing in one direction, and in the opposite direction there is a dot, or point, that marks the endpoint.
A line segment has two points on either side and does notgo on forever.
A geometrical construction can be made with with a straight edge and a compass.
A ruler can be classed as a straight edge.
A straight edge
Usually a pair of compasses, a protractor and a straight edge such as a ruler.

Geometric figures can be drawn using a compass and a straight edge. This is commonly known as ruler and compass construction.

A straight edge looks like a ruler.
A geometric figure drawn using a straight edge and a compass is a construction that adheres to the principles of classical geometry. These figures are created by using the straight edge to draw straight lines and the compass to draw arcs and circles, allowing for precise measurements and relationships between points. Common examples include triangles, circles, and polygons, which can be constructed based on specific rules and theorems. This method emphasizes the use of basic geometric tools to explore and illustrate mathematical concepts.
