Quiz
an imaginary line in the middle of an object around which the object revolves
axe
(geometry) an arbitrary straight line that passes through the center of a symmetrical object or around which an object spins
axe
a mark or an object formed by two short lines or pieces crossing each other
croix
(geometry) a straight line that joins the opposite corners of a flat shape at an angle
diagonale
(geometry) a shape that consists of a line alternating its direction to left and right
zigzag
a straight line that is terminated by a secondary line at each end, resembling the letter H
balbis, ligne en H
a straight line with one endpoint that extends infinitely in the other direction
rayon
a portion of a straight line that is defined by two distinct endpoints
segment de droite, segment linéaire
(mathematics) any of the pair of geometric figures such as lines or planes which do not meet or intersect
parallèle
a line or structure that meets another at a right angle, creating a 90-degree intersection
perpendiculaire, perpendicularité
a straight line that touches a curve or surface at exactly one point, known as the point of tangency
tangente
a pair of adjacent angles formed by two intersecting lines, which add up to 180 degrees
paire linéaire
an angle that measures between 0 and 90 degrees, which is less than a right angle (90 degrees)
angle aigu, angle acut
an angle that measures more than 90 degrees but less than 180 degrees
angle obtus
an angle that measures exactly 180 degrees, which is the same as a straight line
angle plat, angle droit
an angle that measures either less or more that 90 degrees
angle oblique, angle non droit
an angle that measures greater than 180 degrees but less than 360 degrees
angle réflexe, angle de reflexion
a complete revolution or turn around a fixed point or axis, covering a 360-degree angle
rotation complète, révolution complète
an angle measured counterclockwise from the initial side of a reference angle in standard position, usually expressed in degrees or radians
angle positif, angle mesuré dans le sens antihoraire
an angle measured clockwise from the initial side of a reference angle in standard position, usually expressed in degrees or radians
angle négatif, angle mesuré dans le sens des aiguilles d'une montre
two angles that share a common vertex and a common side, but do not overlap, and are not in a straight line
angles adjacents, angles contigus
the measure of the tilt between two lines or surfaces in two-dimensional space, typically given in degrees or radians
angle planaire, angle de plan
a shape, line or surface that is hollow and is rounded inward
concavité
(geometry) a shape formed when a circular cone is intersected by a plane
section conique
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
croissant de lune
(geometry) a curved shape or design that gradually winds around a center or axis
spirale
(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
parabole
a geometric curve formed by the intersection of a plane with two cones, resulting in two symmetrical branches
hyperbole
a continuous curve that does not intersect itself, and can be traced without lifting the pen or pencil from the paper
courbe simple
a curve that intersects itself, or has overlapping segments, requiring the pen or pencil to be lifted from the paper while tracing it
courbe non simple, courbe auto-intersectante
a curve that does not intersect itself and has distinct endpoints, meaning it does not form a closed shape or loop
courbe ouverte, courbe non fermée
a curve that begins and ends at the same point, forming a closed loop
courbe fermée, courbe clôturée
