Basic geometry. Basic geometry is the study of points, lines, angles, surfaces, and solids.The study of this topic starts with an understanding of these. Let's define them. Point: A point is a location in space. It is represented by a dot. Point are usually named with a upper case letter. For example, we refer to the following as "point A" Line: A line is a collection of points that extend forever. We put two points in order to name the line as line AF. Line segment: A line segment is part of a line. Ray: A ray is a collection of points that begin at one point (an endpoint) and extend forever on one direction. Angle: Two rays with the same endpoint is an angle. Plane: A plane is a flat surface like a piece of paper. Parallel lines When two lines never meet in space or on a plane no matter how long we extend them, we say that they are parallel lines The following lines are parallel.
Vertex: The point where two rays meet is called a vertex. Geometry. Geometry is all about shapes and their properties. If you like playing with objects, or like drawing, then geometry is for you! Geometry can be divided into: Point, Line, Plane and Solid A Point has no dimensions, only position A Line is one-dimensional A Plane is two dimensional (2D) A Solid is three-dimensional (3D) Why?
Why do we do Geometry? Plane Geometry Plane Geometry is all about shapes on a flat surface (like on an endless piece of paper). Perimeter General Drawing Tool Polygons A Polygon is a 2-dimensional shape made of straight lines.

Geometry. Shape and Space in Geometry. The National Council of Teachers of Mathematics recognizes the importance of geometry and spatial sense in its publication Curriculum and Evaluation Standards for School Mathematics (1989). Spatial understandings are necessary for interpreting, understanding, and appreciating our inherently geometric world.
Insights and intuitions about two- and three-dimensional shapes and their characteristics, the interrelationships of shapes, and the effects of changes to shapes are important aspects of spatial sense. Children who develop a strong sense of spatial relationships and who master the concepts and language of geometry are better prepared to learn number and measurement ideas, as well as other advanced mathematical topics. (p. 48) And in its Principles and Standards for School Mathematics, NCTM has placed the Standard for Geometry at every grade level from preK to 12. Arithmetic is an important corner of mathematics, but too often we neglect the rest of the field. So teachers, be watchful.

The simplest geometric idea is the point, and then the line, the plane, and the solid. Shapes like circles, squares, rectangles, and triangles are flat, and we can think of them as being parts of a plane, flat like a drawing.
Shapes like spheres, cubes, and pyramids are solid, and we can think of them as being part of the whole universe - as indeed any real object is. Pyramid When people work with geometric shapes, there are some things they often want to know about them. We'd like to know how big they are (their area or their volume), and how long their edge is or how big their surface is (their perimeter or their surface area). People like the Babylonians and the Egyptians and the Chinese figured out a lot of ways of calculating the size of different shapes when you only know a few things about that shape. But how can we be sure that our ways of figuring the size of shapes are always going to work? Physics Chemistry Biology Science for Kids home page History for Kids home page or.
