#### Objective

Learning competence
Students are aware of the basic properties of trigonometric functions. They know how to solve rectangular and oblique triangles. They are familiar with the more common plane figures and solid bodies and know how to calculate their areas and volumes.

Working community competence
Students are able to present the stages of geometrical problem solving orally and in writing and also via online and virtual communication. They are competent in graphical illustration of mathematical models. Students are able to function in various groups and teams and to manage teams, which seek solutions for geometrical problems.

Quality management competence
Students are able to apply both exact and approximate methods to determine the correctness of mathematical work. Students know how to estimate the inaccuracy of measurements and take it into consideration.
