Symmetry in Mathematics and Art

Posted on by

On April 23, 2019, the topic “Symmetry in Mathematics and Art” was presented at Teodor Trayanov’s 10th School in Sofia. During the hour Neda, Koya and Toni introduced the students of the 5th grade with several types of symmetry in mathematics and art. With the help of dynamic resources created with Geogebra, the pupils made an author’s works.
