ax, linie imaginară
(geometry) an arbitrary straight line that passes through the center of a symmetrical object or around which an object spins
axă
a mark or an object formed by two short lines or pieces crossing each other
cruce
(geometry) a straight line that joins the opposite corners of a flat shape at an angle

(geometry) a shape that consists of a line alternating its direction to left and right
zigzag, zigzag (în geometrie)
a straight line that is terminated by a secondary line at each end, resembling the letter H
balbis, linie în H
a straight line with one endpoint that extends infinitely in the other direction
rază
a portion of a straight line that is defined by two distinct endpoints
segment de dreaptă, traseu liniar
(mathematics) any of the pair of geometric figures such as lines or planes which do not meet or intersect
paralel
a line or structure that meets another at a right angle, creating a 90-degree intersection
perpendicular, perpendicularitate
a straight line that touches a curve or surface at exactly one point, known as the point of tangency
tangentă
a pair of adjacent angles formed by two intersecting lines, which add up to 180 degrees
pereche liniară
an angle that measures between 0 and 90 degrees, which is less than a right angle (90 degrees)
unghi acut, unghi ascuțit
an angle that measures more than 90 degrees but less than 180 degrees
unghi obtuz
an angle measuring exactly 90 degrees
unghi drept, unghi de nouăzeci de grade
an angle that measures exactly 180 degrees, which is the same as a straight line
unghi drept, unghi plat
an angle that measures either less or more that 90 degrees
unghi oblic, unghi ne drept
an angle that measures greater than 180 degrees but less than 360 degrees
unghi reflex, unghi mai mare de 180 grade
a complete revolution or turn around a fixed point or axis, covering a 360-degree angle
rotire completă, revoluție completă
an angle measured counterclockwise from the initial side of a reference angle in standard position, usually expressed in degrees or radians
unghi pozitiv, unghi măsurat în sens anti-orar
an angle measured clockwise from the initial side of a reference angle in standard position, usually expressed in degrees or radians
unghi negativ, unghi măsurat în sensul acelor de ceasornic
two angles that share a common vertex and a common side, but do not overlap, and are not in a straight line
unghiuri adiacente, unghiuri învecinate
the measure of the tilt between two lines or surfaces in two-dimensional space, typically given in degrees or radians
unghi plan, unghi în plan
a shape, line or surface that is hollow and is rounded inward
concavitate, deprimare
(geometry) a shape formed when a circular cone is intersected by a plane
secțiune conică
a curved shape with narrow points at the ends that appears wider in the middle, like the shape of the moon in its first and last quarters
lună crescătoare, crescente
(geometry) a curved shape or design that gradually winds around a center or axis
spirală
(geometry) a symmetrical open curve that is similar to the path of an object thrown into the air passes till it falls back to earth
parabolă
a geometric curve formed by the intersection of a plane with two cones, resulting in two symmetrical branches
hiperbolă
a continuous curve that does not intersect itself, and can be traced without lifting the pen or pencil from the paper
curbă simplă
a curve that intersects itself, or has overlapping segments, requiring the pen or pencil to be lifted from the paper while tracing it
curbă nesimplă, curbă auto-intersectantă
a curve that does not intersect itself and has distinct endpoints, meaning it does not form a closed shape or loop
curbă deschisă, curbă neînchisă
a curve that begins and ends at the same point, forming a closed loop
curbă închisă, curbă feronieră
