What is a circle?
A circle is the set of all the points that are the same (arbitrary) distance (called the radius) from some (arbitrary) point (called the center).
Are three points always contained in exactly one plane?
Three points determine exactly one plane.That means that if you bring me a plane, then some or all of my three points may ormay not lie in your plane. But if you bring me three points, then I can always draw aplane in which all of your points lie, and I can also guarantee that it's the only one.By the way ... three points also determine exactly one circle.
Can a triangle have a negative side?

What are facts about arrowheads made by native Americans?
In North America, arrowheads were originally made of obsidian (volcanic glass), bone, copper, flint, chert or carved in one piece with the arrowshaft wood. The material used depended entirely on what was available locally, or what could be traded from other native groups. Native copper was found around the Great Lakes and could be simply pounded flat with a hammer stone, then worked into shape and sharpened. Obsidian was used on the west coast and the Great Basin area; flint was used on the east coast, in the Upper Midwest, on the west coast, in the Great Basin and the south-west. Bone, particularly deer leg bone, made a reasonably sharp point. The Powhatan and other east coast people also made wooden points which were carved in one piece with the shaft, which was often of hickory. Almost all native groups ceased making arrowheads of these materials as soon as white traders brought ready-made metal points, or sheets of brass or iron and tools for the natives to make their own metal points. By the 1850s the Plains tribes had mostly lost the knowledge of how to make stone points - the Crows later claimed that flint points found in their region were made by a mythical race of dwarfs. Reliance on metal arrowheads from traders was widespread by that time, except in areas where traders had not ventured; these included the California tribes and many of the south-western groups. The Californian Yahi native called Ishi continued to make tiny stone points (and beautiful glass arrowheads - the nearest thing to obsidian) up to his death. The Pawnee made some arrow points from sheet brass or old brass containers brought by settlers. The Lakota and other Plains tribes used barrel hoops or the support hoops from wagons to make iron points, using hacksaws and files obtained in trade.
What is the value of Indian arrowheads?
The worth varies from as low as $5 to $20,000, but the truth lies in the quality of them as whether the tip is broken and other quality descriptions. Condition: Any breaks, chips or even thick scratches can ruin value. This is the most common problem with arrowheads. Form: If the arrowhead has a classic point, value rises. Size: Larger arrowheads win the bucks. Thinness: The arrowheads with thinner points earn more value but it can also depend on the specific type of arrowhead. Flaking: Technique matters;It depends what type of technique was used and the quality. Some better-bucks techniques are oblique and transverse. Minerals and Color: As many states see gray, brown and other other darker, dusker colors, other colors seem to be better.
