This application contains the first part of the course of terminal S of solid geometry.

We study the relative positions of objects in space (straight / straight, straight / plans and maps / plans) definitions of parallelism and orthogonality and the properties thereto.

We define the pins of the space and the coordinates of points and vectors. middle of the formulas is generalized and the length of a segment known so far in the plan.

It then discusses the concepts of colinaires and coplanar vectors and vector characterizations of lines and planes.

We finish the course by parameterization of lines and planes.

The course is illustrated with examples and exercises corrected.

The concepts of inner product and Cartesian equations plan are studied in the next class.
