Quiz
an imaginary line in the middle of an object around which the object revolves
axel, föreställt linje
(geometry) an arbitrary straight line that passes through the center of a symmetrical object or around which an object spins
axel
a mark or an object formed by two short lines or pieces crossing each other
kors
(geometry) a straight line that joins the opposite corners of a flat shape at an angle
diagonal
(geometry) a shape that consists of a line alternating its direction to left and right
zickzack, zickzack (i geometri)
a straight line that is terminated by a secondary line at each end, resembling the letter H
balbis, H-formad linje
a straight line with one endpoint that extends infinitely in the other direction
stråle
a portion of a straight line that is defined by two distinct endpoints
linjesegment, sträcka på en linje
(mathematics) any of the pair of geometric figures such as lines or planes which do not meet or intersect
parallell
a line or structure that meets another at a right angle, creating a 90-degree intersection
vinkelrät, vinkelräthet
a straight line that touches a curve or surface at exactly one point, known as the point of tangency
tangent
a pair of adjacent angles formed by two intersecting lines, which add up to 180 degrees
linjärt par
an angle that measures between 0 and 90 degrees, which is less than a right angle (90 degrees)
spetsig vinkel, vinkeln skarp
an angle that measures more than 90 degrees but less than 180 degrees
obtus vinkel
an angle measuring exactly 90 degrees
rät vinkel, vinkel på nittio grader
an angle that measures exactly 180 degrees, which is the same as a straight line
rak vinkel, plan vinkel
an angle that measures either less or more that 90 degrees
oblik vinkel, icke-rät vinkel
an angle that measures greater than 180 degrees but less than 360 degrees
reflexvinkel, vinkel större än 180 grader
a complete revolution or turn around a fixed point or axis, covering a 360-degree angle
full rotation, full revolution
an angle measured counterclockwise from the initial side of a reference angle in standard position, usually expressed in degrees or radians
positiv vinkel, vinkel mätt moturs
an angle measured clockwise from the initial side of a reference angle in standard position, usually expressed in degrees or radians
negativ vinkel, vinkel mätt medurs
two angles that share a common vertex and a common side, but do not overlap, and are not in a straight line
intilliggande vinklar, grannvinklar
the measure of the tilt between two lines or surfaces in two-dimensional space, typically given in degrees or radians
planvinkel, vinkel i ett plan
a shape, line or surface that is hollow and is rounded inward
konkavitet, hål
(geometry) a shape formed when a circular cone is intersected by a plane
konisk sektion
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
halvmåne, crescentform
(geometry) a curved shape or design that gradually winds around a center or axis
spiral
(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
parabola
a geometric curve formed by the intersection of a plane with two cones, resulting in two symmetrical branches
hyperbel
a continuous curve that does not intersect itself, and can be traced without lifting the pen or pencil from the paper
enkel kurva
a curve that intersects itself, or has overlapping segments, requiring the pen or pencil to be lifted from the paper while tracing it
icke-enkel kurva, självskärande kurva
a curve that does not intersect itself and has distinct endpoints, meaning it does not form a closed shape or loop
öppen kurva, icke sluten kurva
a curve that begins and ends at the same point, forming a closed loop
sluten kurva, stängd kurva
