Dějiny Prahy jsou spjaté i s jejím německým obyvatelstvem a jeho kulturou. SAMSA tě zavede na místa, jež nesou stopu této „německé Prahy“ – jsou spojená s činností německy mluvících architektů, výtvarných umělců, literátů, hudebníků, spolků, škol a dalších institucí. U každého místa appka nabízí německý text se základním popisem, informacemi k jeho dějinám a roli v kulturním životě, a několik současných i historických fotografií. Výklad stojí na ověřených zdrojích, ale nezahltí tě. Objevuj s mobilem v ruce pozapomenutou součást dějin města! Aplikace vznikla v rámci společného projektu Shromáždění německých spolků v ČR a studentů i učitelů germanistiky na Filozofické fakultě Univerzity Karlovy. Počet hesel bude průběžně rozšiřován.

About

Geometric Concepts

Features
Read full description

Geometric Concepts builds a solid foundation in geometry by clearly defining and illustrating fundamental objects—points, lines, rays, segments, and angles. The app surveys angle types in the plane (acute, right, obtuse, straight, and reflex) and explains angle relationships such as complementary, supplementary, vertical, and adjacent. It introduces congruence for segments and angles, using precise notation and step-by-step examples to show how to recognize and prove congruence. Interactive diagrams and worked examples help build intuition, while a concise glossary clarifies symbols and terms. Learning is reinforced through tiered quizzes, instant feedback, and guided proof analysis that breaks problems into manageable steps. The app cycles content for review and provides progressively challenging practice to strengthen reasoning and problem-solving skills.
