Cissoid

[Sarah]

A curve invented by Diocles, for the purpose of solving twocelebrated problems of the higher geometry; viz., to trisect a planeangle, and to construct two geometrical means between two givenstraight lines.

@sarah hi Good evening to you please
What is the meaning of stonge please

In geometry, a cissoid ( is a plane curve generated from two given curves C1, C2 and a point O. Let L be a variable line passing through O and intersecting C1 at P1 and C2 at P2. Let P be the point on L so that Then the locus of such points P is defined to be the cissoid of the curves C1, C2 relative to O.
