1.I made a pattern and my lines are straight,diagonal. and I use my favorite color like blue and red and yellow and some brown. I use large triangles and big triangles some circles and more triangles and more circles that are big and small and very small.

2.in the corners they are blue and they are sumechecal in all for  corners.     the small and some big I was successful using symmetry because in all the for corners all the corners are the same the same color the same shape.
