Designed to inform readers about the formal development of Euclidean geometry and to prepare prospective high school mathematics instructors to teach Euclidean geometry, this text closely follows Euclid's classic, Elements. The text augments Euclid's statements with appropriate historical commentary and many exercises -- more than 1,000 practice exercises provide readers with hands-on experience in solving geometrical problems.In addition to providing a historical perspective on plane geometry, this text covers non-Euclidean geometries, allowing students to cultivate an appreciation of axiomatic systems. Additional topics include circles and regular polygons, projective geometry, symmetries, inversions, knots and links, graphs, surfaces, and informal topology. This republication of a popular text is substantially less expensive than prior editions and offers a new Preface by the author.

Nice sink caddy
Color: Gold, Color: Gold
It was exactly as described- looks nice on my counter. I haven’t bought the scrub brush I want yet to put in the taller space but it def dries fast anytime water gets on it. I like the look on my counter space. It’s not flimsy, I like the color of the gold.

Effective!!
Color: Black, Color: Black
This caddy keeps my sink organized. It absorbs the water when I place my sponges on it and its super easy to keep clean. I squeeze as much waster as I can from the sponges so it doesn't wear out. I've had this a little under a year and it has held up exceptionally well.

Perfect for beside any sink even dorms
Color: Black
I bought this for my son for his dorm room for his sponge for washing dishes and for him to put his dish soap and his hand soap for everything that he could keep it all tidy because he’s actually quite organized and he actually really liked it and it looked very neat. It’s easy to clean. It wasn’t too big everything fit perfectly for the Myers hand soap, and dish soap. The color is neutral almost masculine is gray and black. And there is no issue of it falling because he kept it on a side table away from the sink so that nobody else would use it so it would be just his.
So It was altogether and kept everything organized. He really liked it.

Less mess, more style!
Color: Gold, Color: Gold
So happy with this purchase! I was a tiny bit wary buying an item without any reviews yet, however I saw that the other caddies from this brand all had many positive reviews and seemed to be good quality. The diatomaceous earth base of this caddy elevated this option to me, so I went for it. I've had it out for a few days and am extremely happy that I went with this option! It absorbs water super quickly, so there are no more rings and residue left on the top of my sink, and it makes my countertop look that much more cute and put-together. Heads up it is a little deep compared to some other trays/caddies; I knew this ahead of time so planned to put it directly to the side of my sink so that it did not overlap. I think the size is worth it, since it accommodates about 2 soap products and has plenty of adjustable room for bottle brushes, sponges, drain stoppers, and whatever other items you need. Overall, I highly recommend!

Sturdy and does the job well.
Color: Black
Very stable. Have a narrow ledge on my sink and it balances great without falling. Holds all my sponges and brushes and dish soap. Hasn’t rusted and I’ve had it for a while now. Looks nice on my sink. Keeps my counters dry and my sponges mold free.
