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).
The camp at Monowitz (also called Monowitz-Buna or Auschwitz III) was constructed and began housing inmates on October 30, 1942, the first concentration camp to be financed and built by private industry.
