Тест
an imaginary line in the middle of an object around which the object revolves
ось
(geometry) an arbitrary straight line that passes through the center of a symmetrical object or around which an object spins
ось
a mark or an object formed by two short lines or pieces crossing each other
символ хрестик
(geometry) a straight line that joins the opposite corners of a flat shape at an angle
диагональ
(geometry) a shape that consists of a line alternating its direction to left and right
зигзаг
a straight line that is terminated by a secondary line at each end, resembling the letter H
балбис
a straight line with one endpoint that extends infinitely in the other direction
луч
a portion of a straight line that is defined by two distinct endpoints
отрезок прямой
(mathematics) any of the pair of geometric figures such as lines or planes which do not meet or intersect
параллель
a line, segment, or structure that meets another at a right angle, creating a 90-degree intersection
перпендикуляр
a straight line that touches a curve or surface at exactly one point, known as the point of tangency
тангенс
a pair of adjacent angles formed by two intersecting lines, which add up to 180 degrees
линейная пара
an angle that measures between 0 and 90 degrees, which is less than a right angle (90 degrees)
острый угол
an angle that measures more than 90 degrees but less than 180 degrees
тупой угол
an angle that measures exactly 180 degrees, which is the same as a straight line
прямой угол
an angle that measures either less or more that 90 degrees
косой угол
an angle that measures greater than 180 degrees but less than 360 degrees
рефлексный угол
a complete revolution or turn around a fixed point or axis, covering a 360-degree angle
полный поворот
an angle measured counterclockwise from the initial side of a reference angle in standard position, usually expressed in degrees or radians
положительный угол
an angle measured clockwise from the initial side of a reference angle in standard position, usually expressed in degrees or radians
отрицательный угол
two angles that share a common vertex and a common side, but do not overlap, and are not in a straight line
смежные углы
the measure of the tilt between two lines or surfaces in two-dimensional space, typically given in degrees or radians
плоский угол
a shape, line or surface that is hollow and is rounded inward
вогнутость
(geometry) a shape formed when a circular cone is intersected by a plane
коническое сечение
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
полумесяц
(geometry) a curved shape or design that gradually winds around a center or axis
спираль
(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
парабола
a geometric curve formed by the intersection of a plane with two cones, resulting in two symmetrical branches
гипербола
a continuous curve that does not intersect itself, and can be traced without lifting the pen or pencil from the paper
простая кривая
a curve that intersects itself, or has overlapping segments, requiring the pen or pencil to be lifted from the paper while tracing it
несложная кривая
a curve that does not intersect itself and has distinct endpoints, meaning it does not form a closed shape or loop
открытая кривая
a curve that begins and ends at the same point, forming a closed loop
замкнутая кривая
