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 term Concentration camp was first used by the British in the Boer wars. this was very different form the concentration camps used in Nazi Germany. they were not death camps but camps in which the family of Boer rebels were imprisoned so that they could not aid the rebels.
