6  While listening to links  Below draw some acute angles. Use the degrees listed. Do this in your coil note book. Use ruler and a protractor.  A) 20 * b) 75* c) 50*  http://www.youtube.c om/watch?v=j8sF8k6D nI&feature=related http://www.youtube.c om/watch?v=j8sF8k6D nI&feature=related  http://www.youtube.c om/watch?v=yptZt9hw rzU&feature=related http://www.youtube.c om/watch?v=yptZt9hw rzU&feature=related

7  Use a ruler and a protractor. Create these angles in your coil notebook.  A) 120*  B) 95*  C) 170*  Watch the link about obtuse angles.  http://www.youtube. com/watch?v=LWdL CvKmCAY http://www.youtube. com/watch?v=LWdL CvKmCAY
