The first characteristic is also the most complex: composition. The composition usually involves smaller geometric shapes that are repeated, creating rhythm. A grid of either equilateral triangles or squares is used as a foundation, but
sometimes a twist on the triangle grid-a hexagonal grid-is used instead. Circles, squares, and straight lines provide the
basis for the pattern, which is interlaced, combined, and duplicated in order to create a beautiful design. In mathematics,
these grids of repeated figures are called tessellations, a word which is derived from the Latin word tessere, meaning
“pieces of mosaic." A tessellation repeats a polygon over and over to tile a plane.

Excerpt from urban agriculture terri roberts telling a which of these is written in the narrative mode? a) the most important aspect of urban agriculture is the way it fosters community. people who lived down the block from one another had never spoken before we planted the garden. now, neighbors wave to each other on the street and have a real relationship. b) urban agriculture is an undertaking that our city just cannot afford at this time. how can we spend millions of dollars to clear the land and build a garden when we don’t have enough money in the budget to get our children the education they deserve? it seems like an expense that will just have to wait. c) i had never been to a farm before my class took a trip to a city garden. when we arrived, i spotted chickens walking around. there were even two goats grazing on a patch of grass. the tour guide explained the importance of city farmers while showing us around the tiny garden. she handed me a fresh green bean to try. it tasted really sweet! d) i think that urban agriculture is a great solution to many of our city's problems. it’s difficult for many families to find fresh, affordable produce in the city. with a city garden right down the road, it would be easy for people to get the vegetables and fruits they need. this would also our citizens begin to adopt healthier lifestyles.
