[4eso] Geometry: equations of a straight line & trigonometry

The post contains the materials to develop 15 sessions working with vectors, straight lines and trigonometric ratios.
Topics worked:
Vectors: coordinates, direction, orientation, magnitude, operations.
Straight lines: equations (vector, parametric, continuous, explicit, general).
Trigonometry: definition of trigonometric ratios.
Problem solving, use of GeoGebra.

sessions 1 to 5: vectors

sessions 6 to 9: straight lines

sessions 10 to 15: trigonometry
