In this chapter the reader can find exercises for practising basic geometrical concepts such as recognizing different types of polygons, measuring angles, finding the perimeter and the area for polygons, using the Pythagorean theorem and Heron’s formula. In addition to the tasks in the Intro part, these exercises provide further opportunity to get familiar with the Logifaces Sets and the blocks themselves. [br]Additional practical information relating to this chapter:[br][list][*]If not mentioned otherwise, the parameters of the blocks are measured in standard units[br][/*][*]The notation |AB| stands for the length of the segment AB[/*][/list]
