острый угол, угол остроты
an angle that measures more than 90 degrees but less than 180 degrees
тупой угол

an angle measured counterclockwise from the initial side of a reference angle in standard position, usually expressed in degrees or radians
положительный угол, угол
an angle measured clockwise from the initial side of a reference angle in standard position, usually expressed in degrees or radians
отрицательный угол, 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, прилежащие углы
the measure of the tilt between two lines or surfaces in two-dimensional space, typically given in degrees or radians

(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, самопересекающаяся кривая
a curve that does not intersect itself and has distinct endpoints, meaning it does not form a closed shape or loop
открытая кривая, не замкнутая кривая
a curve that begins and ends at the same point, forming a closed loop
замкнутая кривая, закрытая кривая
