Hello, Can you answer question 1 a and b?

Written Assignment 6: Reflections and their Applications 1. Tessellation by Glide Reflection Technique. a) The left side of the dashed square with sides of length 9 units has been modified. Apply a glide reflection to the modified side about the line / and by a horizontal translation (9,0). This creates a pattern that tessellates the plane. Highlight its four "sides" and color the interior of the pattern. b) Use the pattern created above to tessellate the following grid. Alternate colors. 2. Go to the website http://www.mcescher.com/gallery/symmetry/ and find the following M. C. Escher's tessellation paintings.
