![]() They were also used to calculate and record wind readings and provided a unique form of communication similar to ship flags at sea. The f irst Chinese kites were used for measuring distances, which was useful information for moving large armies across difficult terrain. They were designed to mimic a bird's natural flight. The first kites were what we today would call prototype kites: they were made of light wood and cloth. Mainly, they were used for military purposes. Kites played a role in providing military intelligence for the Chinese forces. The period saw many attacks from foreign powers, as well as civil unrest. The kites were exclusive to China for many years before the knowledge of how to make and use them advanced. Kites were invented in the early Warring States Period (475 - 221 B.C.) by Mozi and Lu Ban, two philosophers who came after the teachings of Confucius. Some kites will have LED lights attached to allow for night flights and fun light shows. They will often resemble real animals and members of the Chinese Zodiac. ![]() Today, elaborate and large designs can be seen flying above parks in China. They were often made to resemble the shapes of birds. The kite you probably flew as a kid looks a bit different to the original Chinese kites and even the kites of modern China.Ī Chinese kite in ancient times would have used simple materials such as wood and cloth. Since its invention, there have been many adaptations to the kite by various cultures around the world. The kite is believed to have originated in China. It's the famous Chinese kite and its long history of cultural significance begins thousands of years ago. ![]() This ancient relic brings the colors and patterns of the ancient dynasties to the city skies of modern China and the world. But beneath the clouds there is a Chinese art form that has glided through history. When we talk about the skies above China, we are often referring to topics like pollution or busy airlines. So all other quadrilaterals are irregular.Flying kites is a popular pastime in China. The only regular (all sides equal and all angles equal) quadrilateral is a square. and that's it for the special quadrilaterals. one of the diagonals bisects (cuts equally in half) the other.the diagonals, shown as dashed lines above, meet at.The KiteĮach pair is made of two equal-length sides that join up. (the US and UK definitions are swapped over!)Īn Isosceles trapezoid, as shown above, has left and right sides of equal length that join to the base at equal angles. NOTE: Squares, Rectangles and Rhombuses are allĪ trapezoid (called a trapezium in the UK) has a pair of opposite sides parallel.Īnd a trapezium (called a trapezoid in the UK) is a quadrilateral with NO parallel sides: Also opposite anglesĪre equal (angles "A" are the same, and angles "B" The ParallelogramĪ parallelogram has opposite sides parallel and equal in length. In other words they "bisect" (cut in half) each other at right angles.Ī rhombus is sometimes called a rhomb or a diamond. The RhombusĪ rhombus is a four-sided shape where all sides have equal length (marked "s").Īlso opposite sides are parallel and opposite angles are equal.Īnother interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. The SquareĪ square has equal sides (marked "s") and every angle is a right angle (90°)Ī square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length). The little squares in each corner mean "right angle"Ī rectangle is a four-sided shape where every angle is a right angle (90°).Īlso opposite sides are parallel and of equal length. Let us look at each type in turn: The Rectangle Some types are also included in the definition of other types! For example a square, rhombus and rectangle are also parallelograms. There are special types of quadrilateral: They should add to 360° Types of Quadrilaterals Try drawing a quadrilateral, and measure the angles. interior angles that add to 360 degrees:.(Also see this on Interactive Quadrilaterals) Properties
