An Interior Angle is an angle inside a shape. Note: When we add up the Interior Angle and Exterior Angle we get a straight line, 180Â°. (See Supplementary Angles).
The Concentration Camp at Dachau was opened 22 March 1933, with the arrival of about 200 prisoners from Stadelheim Prison in Munich and the Landsberg fortress (where Hitler had written Mein Kampf during his imprisonment).
Auschwitz was the largest camp established by the Germans. It was a complex of camps, including a concentration, extermination, and forced-labor camp. It was located at the town of Oswiecim near the prewar German-Polish border in Eastern Upper Silesia, an area annexed to Germany in 1939. Auschwitz I was the main camp and the first camp established at Oswiecim. Auschwitz II (Birkenau) was the killing center at Auschwitz. Trains arrived at Auschwitz-Birkenau almost daily with transports of Jews from virtually every German-occupied country of Europe. Auschwitz III, also called Buna or Monowitz, was established in Monowice to provide forced laborers for nearby factories, including the I.G. Farben works.
