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).
Not all concentration camps in Germany were in isolated locations. Take Oranienburg, for example. This concentration camp was opened in 1933 as one of the first detention centers built by the Nazis. Located near Berlin, right in the town of Oranienburg, the Nazis transformed an old factory into a detention center.
