In geometry, a three-dimensional space (3D space, 3-space or, rarely, tri-dimensional space) is a mathematical space in which three values (coordinates) are required to determine the position of a point. Most commonly, it is the three-dimensional Euclidean space, that is, the Euclidean space of dimension three, which models physical space.
For a plane, the two angles are called its strike (angle) and its dip (angle). A strike line is the intersection of a horizontal plane with the observed planar feature (and therefore a horizontal line), and the strike angle is the bearing of this line (that is, relative to geographic north or from magnetic north). The dip is the angle between a ...
The case of Euclidean and hyperbolic space forms can likewise be reduced to group theory, based on study of the isometry group of Euclidean space and hyperbolic space. For example, the class of two-dimensional Euclidean space forms includes Riemannian metrics on the Klein bottle, the Möbius strip, the torus, the cylinder S 1 × ℝ, along with ...
An octant in solid geometry is one of the eight divisions of a Euclidean three-dimensional coordinate system defined by the signs of the coordinates. It is analogous to the two-dimensional quadrant and the one-dimensional ray. [1] The generalization of an octant is called orthant or hyperoctant.
Since no triangle can have two obtuse angles, γ is an acute angle and the solution γ = arcsin D is unique. If b < c, the angle γ may be acute: γ = arcsin D or obtuse: γ ′ = 180° − γ. The figure on right shows the point C, the side b and the angle γ as the first solution, and the point C ′, side b ′ and the angle γ ′ as the ...
To produce accurate principal vectors in computer arithmetic for the full range of the principal angles, the combined technique [10] first compute all principal angles and vectors using the classical cosine-based approach, and then recomputes the principal angles smaller than π /4 and the corresponding principal vectors using the sine-based ...

Gergonne's approach is to consider the solution circles in pairs. [1] Let a pair of solution circles be denoted as C A and C B (the pink circles in Figure 6), and let their tangent points with the three given circles be denoted as A 1, A 2, A 3, and B 1, B 2, B 3, respectively. Gergonne's solution aims to locate these six points, and thus solve ...
