Euclid's Elements - Book 1 Proposition 2
"To place at a given point a straight line equal to a given straight line."
We have a point and we have a line segment apart from that point.
How do we draw a line segment from that lonely initial point that is exactly the same length as the other line segment?

I may veer off the path in explaining a proposition. That's on me, not Euclid, Heath, Densmore, or Green Lion Press.

Although I mention Indiana University East, Green Lion Press, and other services verbally, graphically, and/or in writing, that is my endorsement of *them*, not their endorsement of me. :-)

No, I don't play bass. But, he probably doesn't do a whole bunch of geometry and trigonometry. :-)
