Задача – една, подходи много

During primary school students are introduced to basic geometry knowledge. As students go through high school, they acquire more and more complex knowledge. In the current article, we present different solutions to one problem, depending on the age and knowledge required to solve the problem. We’ll start with two familiar problems. Then we’ll generalize and we’ll prove a lemma. In the last part we’ll present different problems and their solutions that were born from the first two problems and the lemma.
