SUMMARY

The discussion centers around the concept of a straight line and its sides, specifically addressing a user's confusion regarding the definition of a straight line. A participant clarifies that when a vertical line is drawn, it inherently has a left side and a right side. This explanation aims to resolve the initial user's frustration stemming from a figure in a book that caused misunderstanding.

PREREQUISITES

Understanding of basic geometry concepts
Familiarity with Cartesian coordinates
Knowledge of line properties in mathematics
Ability to interpret geometric figures

NEXT STEPS

Research the properties of straight lines in Euclidean geometry
Explore the concept of dimensions in geometry
Learn about Cartesian coordinate systems and their applications
Study geometric figures and their interpretations in mathematical texts

USEFUL FOR

Students of mathematics, educators teaching geometry, and anyone seeking clarity on geometric concepts related to lines and dimensions.

Homework Statement: On the same straight-line, two other
straight-lines equal, respectively, to
two (given) straight-lines (which meet)
cannot be constructed (meeting) at a
different point on the same side (of
the straight-line), but having the
same ends as the given straight-lines

Relevant Equations: Euclids element's

can someone please explain to me how a straight line has a side? this is so frustrating

never mind I guess this thread might as well be deleted now.

Draw a vertical line, there is going to be a left side and a right side.

The figure that comes with the book confused me into questioning such a simple thing
