In the diagram to the right, Plane P contains points A, B and C.Ĭan you think of some real world objects that satisfy the definition of a plane? At this level of mathematics, that is difficult to do. Thus we have circle A.Ī plane is a flat surface that extends without end in all directions. In the circle to the right, the center is point A. A circle is the set of points that are equidistant from a special point in the plane. Let's revisit the definition of a circle. Thus, it can be stated, every diameter is a chord, but not every chord is a diameter. This is because every diameter passes through the center of a circle, but some chords do not pass through the center. A diameter satisfies the definition of a chord, however, a chord is not necessarily a diameter. It turns out that a diameter of a circle is the longest chord of that circle since it passes through the center. By cutting along chord AB, you are cutting off a segment of pizza that includes this chord. If this circle was a pizza pie, you could cut off a piece of pizza along chord AB. The circle to the right contains chord AB. In geometry, a chord is often used to describe a line segment joining two endpoints that lie on a circle. As you can see, a circle has many different radii and diameters, each passing through its center.Ī chord is a line segment that joins two points on a curve. A straight cut made from a point on the circle, continuing through its center to another point on the circle, is a diameter. A radius is formed by making a straight cut from the center to a point on the circle. Look at the pizza to the right which has been sliced into 8 equal parts through its center. We can look at a pizza pie to find real-world examples of diameter and radius. Thus, the diameter of a circle is twice as long as the radius. If you place two radii end-to-end in a circle, you would have the same length as one diameter. The radius of a circle is the distance from the center of a circle to any point on the circle. A real-world example of diameter is a 9-inch plate. The distance across a circle through the center is called the diameter. Some real world examples of a circle are a wheel, a dinner plate and (the surface of) a coin. Thus, the circle to the right is called circle A since its center is at point A. We will also examine the relationship between the circle and the plane.Ī circle is a shape with all points the same distance from its center. Let's look at the definition of a circle and its parts. Whether you are looking for a rustic look or mid-century modern designs, our store has a rug for you.A circle is an important shape in the field of geometry. With designs ranging from the traditional to the modern and a variety of materials including wool, cotton, silk, polyester, and polypropylene, you're sure to find the perfect rug for your home. They can also be popular in kids' rooms with bright colors to bring a playful spirit to the space.Īt we have geometric rugs to fit any style. Bold patterns bring much-needed visual interest to otherwise stark spaces. These sorts of eye-catching designs are a perfect complement to minimalist décor. Many mid-century modern rugs employ large, repeating patterns like chevrons and lattices. More recently, geometric designs have become popular in modern and contemporary design. This kind of natural rug is an excellent way to add a rustic charm to your home. Kilim rugs from the Caucasus, Turkey, and Afghanistan are known for their striking patterns and bright colors. Though often thought of as a modern trend, geometric designs are found in some of the oldest traditions on earth. On the other hand, a geometric rug with a more minimalist pattern and neutral colors can provide the perfect backdrop for your stylish décor. Paired with contemporary furniture, a brightly colored geometric rug will quickly become the focal point of any room it is in. The bold geometric rugs found at make for a great conversation piece. "Geometric" is a broad category that covers a variety of styles from tribal designs and Moroccan-inspired lattices to ultra-modern patterns.
