Furthermore we try and target to introduce the results of angle and circle concepts, comparing different situations of the same definitions in Galilean and Euclidean planes. %K Galilean Plane %K Special Lines %K Negative Angle %K Parabolic Measure %K Circle %K Cycle %U http://www.oalib.com/paper/3134051
