Quiz
an imaginary line in the middle of an object around which the object revolves
eixo de rotação
(geometry) an arbitrary straight line that passes through the center of a symmetrical object or around which an object spins
Sistema de coordenada cartesiana
a mark or an object formed by two short lines or pieces crossing each other
sinal de multiplicação
(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
ziguezague
a straight line that is terminated by a secondary line at each end, resembling the letter H
balbis
a straight line with one endpoint that extends infinitely in the other direction
raio
a portion of a straight line that is defined by two distinct endpoints
segmento de linha
(mathematics) any of the pair of geometric figures such as lines or planes which do not meet or intersect
paralelo
a line, segment, or structure that meets another at a right angle, creating a 90-degree intersection
perpendicular
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
par linear
an angle that measures between 0 and 90 degrees, which is less than a right angle (90 degrees)
acento agudo
an angle that measures more than 90 degrees but less than 180 degrees
ângulo obtuso
an angle that measures exactly 180 degrees, which is the same as a straight line
ângulo reto
an angle that measures either less or more that 90 degrees
ângulo oblíquo
an angle that measures greater than 180 degrees but less than 360 degrees
ângulo reflexo
a complete revolution or turn around a fixed point or axis, covering a 360-degree angle
rotação completa
an angle measured counterclockwise from the initial side of a reference angle in standard position, usually expressed in degrees or radians
ângulo positivo
an angle measured clockwise from the initial side of a reference angle in standard position, usually expressed in degrees or radians
ângulo negativo
two angles that share a common vertex and a common side, but do not overlap, and are not in a straight line
ângulos adjacentes
the measure of the tilt between two lines or surfaces in two-dimensional space, typically given in degrees or radians
ângulo plano
a shape, line or surface that is hollow and is rounded inward
concavidade
(geometry) a shape formed when a circular cone is intersected by a plane
seção cônica
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
em forma de crescente
(geometry) a curved shape or design that gradually winds around a center or axis
espiral
(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
parábola
a geometric curve formed by the intersection of a plane with two cones, resulting in two symmetrical branches
hipérbole
a continuous curve that does not intersect itself, and can be traced without lifting the pen or pencil from the paper
curva simples
a curve that intersects itself, or has overlapping segments, requiring the pen or pencil to be lifted from the paper while tracing it
curva não simples
a curve that does not intersect itself and has distinct endpoints, meaning it does not form a closed shape or loop
curva aberta
a curve that begins and ends at the same point, forming a closed loop
curva fechada
