because a circle is 360 degrees which means a full turn in a circle. if you get up and spin around one time that is called a 360 turn. if you spin half way that is called a 180 turn.
a squares inside angles are 90 degrees each. since there are four angles they add up to 360 degrees.
a triangles insides angles vary but always equal 180 degrees. it is just the nature of the triangle.
a straight line will always be 180 degrees.
