an angle measured clockwise from the initial side of a reference angle in standard position, usually expressed in degrees or radians
záporný úhel, úhel ve směru hodinových ručiček

(geometry) a curved shape or design that gradually winds around a center or axis
spirála, šroubovice
(geometry) a closed plane curve that has two focal points
elipsa, eliptická křivka

parabola, parabolická křivka
a geometric curve formed by the intersection of a plane with two cones, resulting in two symmetrical branches
hyperbola, hyperbolická křivka
a continuous curve that does not intersect itself, and can be traced without lifting the pen or pencil from the paper
jednoduchá křivka, neprotínající se křivka
a curve that intersects itself, or has overlapping segments, requiring the pen or pencil to be lifted from the paper while tracing it
nesimple křivka, sebeprotínající křivka
a curve that does not intersect itself and has distinct endpoints, meaning it does not form a closed shape or loop
otevřená křivka, otevřený oblouk
a curve that begins and ends at the same point, forming a closed loop
