curvilinear

There are the degrees of direction of line, curvilinear or angular.

The same principle is true of designs upon the curvilinear plan.

It would be the same with the quadrature of curvilinear areas.

Who can decide between rectilinear and curvilinear geometry?

Who shall decide between rectalinear and curvilinear geometry?

Out of "Brandt" I defy you to get any curvilinear suggestion.

Its germ was the Cartesian vortices, suggested by the curvilinear forms of iron filings in the vicinity of magnetic poles.

It is possible to add to the work in pure geometry some work in the mensuration of the curvilinear figures shown in these designs.

The curvilinear roof gives beauty to the design as well as affording more head room inside than the ordinary straight rafter.

It is covered with a low, continuous, curvilinear roof, and is without side lights.
