i need help with #2 A,B,C, and #3 A,B,C. Also i need help with 1B ?

Written Assignment 7: Dilations and Symmetry 1. Apply the indicated geometric transformations to Figures A and C below. Then draw all lines of symmetry for each of the resulting figures and fill in the blanks. Dilate A by a factor of -1/2 with center Dilate C by a factor of 2 with center at at the origin to obtain B. the origin to obtain D - Rotate A and B angles 90, 180, and - Rotate Cand Dangles 90, 180, and 270" (or -90) with center at the origin. 270" (or -90) with center at the origin. D Number of lines of symmetry: 0 Rotational Symmetry: 4 _-fold symmetry Centrally symmetric? (Circle one) Yes No Number of lines of symmetry: Rotational Symmetry: -fold symmetry Centrally symmetric? (Circle one) Yes/No 2. Determine all symmetries of this figure. a) Draw any lines of symmetry. b) Determine the angles of rotational symmetry: c) Is this figure centrally symmetric? 3. Go to the website http://www.mcescher.com/gallery/mathematical and open M.C. Escher's painting "Circle Limit IV".
