On gloss:

kruvi
x1 is a curve/turn/bend in x2, at locus x3, and defined by set of points/properties x4.

In definition:

bargu
x1 arches/curves over/around x2 and is made of x3; x1 is an arch over/around x2 of material x3.
jbislanu
x1 is an object that has a shape that is three-dimensional and has an axis (especially of symmetry and/or along which cross-sections are mutually similar), or which is approximately a figure of revolution, or which is approximately the result of taking a two-dimensional shape and sweeping it along a curve in a constant way; x1 is (nearly) cylindrical and is made of/has composition x2, having geometric/topological properties x3.
selbargu
x2=b1 arches/curves over/around x1=b2 and is made of x3=b3; x2=b1 is an arch over/around x1=b2 of material x3=b3.
terbargu

zorkru
x1 is a concave curve/turn/bend in x2, at locus x3, and defined by set of points/properties x4.
clenu
x1 is an axis/center curve/extended center (or, possibly metaphorically, focus 'point') of x2 in sense x3
sirjrneuei
x1 (line segment) is a neuein/neusis line segment (line element) constructed from directrix x2 (curve; not necessarily linear) to catchline x3 (curve; not necessarily linear, despite the name) which is inclined toward pole x4 (point) such that it has diastema (length) x5 (li; nonnegative extended-real number).
tsekane
x1 (linear manifold, vector, etc.) is/lies secant to x2 (object, surface, curve, manifold, etc.) passing through or toward points/loci x3 (set of intersected points), by standard/definition/in system x4.
zo'anjo
x1 (linear manifold, vector, etc.) is/lies tangent to x2 (object, surface, curve, manifold, etc.) at point/locus x3, by standard/definition/in system x4.

In notes:

clupa
x1 is a loop/circuit of x2 [material].
jinsa
x1 (object) is clean/pure of material/contaminant/dirt x2 by standard x3.
lumci

kukru
x1 is orthogonal/perpendicular/right/at right angle/rectified/square/normal to x2, where they (are projected to) intersect orthogonally at locus/on set x3, otherwise being utterly distinct (and not even on the same axis/scale) in sense x4
bolstropfedo
