  2. Orientation (geometry) - Wikipedia

    en.wikipedia.org/wiki/Orientation_(geometry)

    Changing orientation of a rigid body is the same as rotating the axes of a reference frame attached to it.. In geometry, the orientation, attitude, bearing, direction, or angular position of an object – such as a line, plane or rigid body – is part of the description of how it is placed in the space it occupies. [1]

  3. Basic State Exam (Russia) - Wikipedia

    en.wikipedia.org/wiki/Basic_State_Exam_(Russia)

    As of 2024 the mathematics exam is divided into two modules: an algebra module and an geometry module. The minimum required score to obtain a certificate is 8 points. [9] Students must score at least 6 points in the Algebra module and at least 2 points in the Geometry module.

  5. Geometry - Wikipedia

    en.wikipedia.org/wiki/Geometry

    In modern mathematics, they are generally defined as elements of a set called space, which is itself axiomatically defined. With these modern definitions, every geometric shape is defined as a set of points; this is not the case in synthetic geometry, where a line is another fundamental object that is not viewed as the set of the points through ...

  6. Free module - Wikipedia

    en.wikipedia.org/wiki/Free_module

    In mathematics, a free module is a module that has a basis, that is, a generating set that is linearly independent. Every vector space is a free module, [ 1 ] but, if the ring of the coefficients is not a division ring (not a field in the commutative case), then there exist non-free modules.

  7. Resolution (algebra) - Wikipedia

    en.wikipedia.org/wiki/Resolution_(algebra)

    In mathematics, and more specifically in homological algebra, a resolution (or left resolution; dually a coresolution or right resolution [1]) is an exact sequence of modules (or, more generally, of objects of an abelian category) that is used to define invariants characterizing the structure of a specific module or object of this category.

  8. Module (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Module_(mathematics)

    In mathematics, a module is a generalization of the notion of vector space in which the field of scalars is replaced by a (not necessarily commutative) ring. The concept of a module also generalizes the notion of an abelian group , since the abelian groups are exactly the modules over the ring of integers .

  9. Bearing (navigation) - Wikipedia

    en.wikipedia.org/wiki/Bearing_(navigation)

    A standard Brunton compass, used commonly by geologists and surveyors to obtain a bearing in the field. In navigation, bearing or azimuth is the horizontal angle between the direction of an object and north or another object. The angle value can be specified in various angular units, such as degrees, mils, or grad. More specifically:
