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).
However, this system was inefficient and not centrally run. The Nazis found a solution by establishing large, purpose-built camps to hold these prisoners. These they called concentration camps. The first camp was established on 1 April 1933 at Dachau, a beautiful south Bavarian town very near Munich. Over the next 12 years, as they invaded and occupied lands all over Europe, the Nazis would build over 20,000 camps. These included concentration camps, transit camps, forced labour or work camps and death camps.
