Many people mistakenly believe that the first time they meet geometric shapes in high school.There they learn their names, properties, and formulas.But in fact, since childhood, any item that a child sees, feels, smells or feels he interacts with it in any other way, it is a geometric figure.Couch, which lies just given birth to a woman - a rectangle, the lamp that gives light midwives - a round figure in the window panes - squares.The list is endless.
Geometric figures directly as an element of science, first encountered students in middle school.You could even say that the geometry begins with them.However, as mentioned above, the first interaction with them occur long before that.Take, for example, point.It is a very small figure in geometry.In addition, it is considered to be the foundation of all the others (the atoms in chemistry).All triangles, squares and other shapes on the drawing consist of any number of points.They have certain properties, each of which has only one piece (no other can not be endowed with them).
can assume that all the geometric shapes are made directly from the line, but what is it?This is the set of points in a row.They can go on forever, because the straight line does not end there.If it is bounded on two sides, it is called a segment.If there is only one restriction, the beam in front of you.Consequently, all the plane figures in geometry consists of segments as components and have an end and a beginning.It should be noted that the line has been split point is the two beams pointing in opposite sides of each other.
Not only is the geometry of planar elements, there are also three-dimensional geometric figures.For their study at school start later, towards the end of his studies, but a person is faced with them again, much sooner.For example, when a child picks up a cube, the cube is holding in his hands.Or, if he looks at the chest, then in front of him cuboid.All volume figures are made up of planes (that is, it is uncertain primary concept, as a straight line).The same parallelepiped has six of such elements.Get acquainted with the plane can be looking at the surface of any desk.But this is only part of it, since there are limitations.Just the same infinite plane as a straight line.
Thus, there is no sphere, where it had not met geometric shapes.Their names are different, they determine the properties and characteristics.For example, the formula for the area of a triangle is not suitable for a rectangle or square.
It is advisable to attach the baby to the geometric shapes before school age.You can make them their own hands and then spread them different drawings on paper (if it is flat elements).But do not reject the three-dimensional figures.On the Internet you can find a variety of educational games associated with it.But you can not put off getting to know them, because everything that we see - geometric shapes.Even the man is one of them!
