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).
Dachau, just outside of Munich, was the first such camp built for political prisoners. Dachau's purpose changed over time and eventually became another brutal concentration camp for Jews. By the end of 1934 Hitler was in absolute control of Germany, and his campaign against the Jews in full swing.
