відрізок прямої, сегмент прямої
a pair of geometric figures, such as lines or planes, that do not meet or intersect, no matter how far they are extended
паралелі, паралельні лінії
a line or structure that meets another at a right angle, creating a 90-degree intersection
перпендикуляр, перпендикулярність
a straight line that touches a curve or surface at exactly one point, known as the point of tangency
дотична
a pair of adjacent angles formed by two intersecting lines, which add up to 180 degrees
лінійна пара

гострий кут, кут гостроти
an angle that measures more than 90 degrees but less than 180 degrees
тупий кут
an angle measuring exactly 90 degrees
прямий кут, кут дев’яноста градусів
an angle that measures exactly 180 degrees, which is the same as a straight line
прямий кут, плоский кут
an angle that measures either less or more that 90 degrees
косий кут, непрямий кут
an angle that measures greater than 180 degrees but less than 360 degrees

повний оберт, повна революція
an angle measured counterclockwise from the initial side of a reference angle in standard position, usually expressed in degrees or radians
позитивний кут, кут
an angle measured clockwise from the initial side of a reference angle in standard position, usually expressed in degrees or radians
негативний кут, кут
two angles that share a common vertex and a common side, but do not overlap, and are not in a straight line
суміжні кути, суміжні кути
the measure of the tilt between two lines or surfaces in two-dimensional space, typically given in degrees or radians
площинний кут, кут у площині
a shape, line or surface that is hollow and is rounded inward
вгнутість, удлибина
(geometry) a shape formed when a circular cone is intersected by a plane
конічна секція
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
півмісяць, кресент
(geometry) a curved shape or design that gradually winds around a center or axis
спіраль
(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
гіпербола
a continuous curve that does not intersect itself, and can be traced without lifting the pen or pencil from the paper
проста крива
a curve that intersects itself, or has overlapping segments, requiring the pen or pencil to be lifted from the paper while tracing it
нескладна крива, самоперетинна крива
a curve that does not intersect itself and has distinct endpoints, meaning it does not form a closed shape or loop
відкрита крива, незамкнена крива
a curve that begins and ends at the same point, forming a closed loop
замкнена крива, закрита крива
