 # Geometry practice 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: Plane Geometry is about flat shapes like lines, circles and triangles ... shapes that can be drawn on a piece of paper Solid Geometry is about three dimensional objects like cubes, prisms, cylinders and spheres. 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. Here are some more: The Circle Circle Theorems (Advanced Topic) Symbols There are many special symbols used in Geometry. Geometric Symbols Congruent and Similar Angles Types of Angles Transformations and Symmetry Transformations: Symmetry: Symmetry Artist
