You can put this solution on YOUR website! Geometry is      and their  . Geometry can be divided into:
 
   - which is about flat shapes like lines, circles and triangles, shapes that can be drawn on a piece of paper 
   - which is about three dimensional objects like cubes, prisms and pyramids 
  ,  ,  and  - terms whose definitions you need to know A
  - has no dimensions, only position A
  -is one-dimensional A
  -is two dimensional (2D) A
  -is three-dimensional (3D) 
 There are many special
  used in geometry. The most common geometrical symbols are: symbol for triangle
  ,  for angle <, for perpendicular lines, for parallel lines , for right angle, for congruent shapes (same shape and size), three dots for “a equals b, therefore b equals a”, and  so on 
 you need to know what
  are A
  is a 2-dimensional shape made of straight lines. example: triangles and rectangles are polygons (you find out what other polygons we have)
 Solid shapes- three-dimensional shapes ....and so on
 most important is to know Pythagoras' Theorem which is very often used
