Geometry
 The Graphics command generates all kinds of 2D shapes:
 
  
  
   | Out[1]= |  | 
  
  
 Many geometric objects take a series of coordinates (lists) as arguments:
 
  
  
   | Out[2]= |  | 
  
  
 Pass in a list with directives to combine graphics and change their styles:
 
  
  
   | Out[3]= |  | 
  
  
 
   
  Generate triangles with commands like SASTriangle:
  (Type ESCdegESC for the ° symbol.) 
  
   
   
    | Out[1]= |  | 
   
   
  Properties like area can be computed directly:
  
   
   
    | Out[2]= |  | 
   
   
  Pass this expression into Graphics: 
  
   
   
    | Out[3]= |  | 
   
   
  
 
   
  Similarly, you can use Graphics3D to display 3D objects:
  
   
   
    | Out[1]= |  | 
   
   
  Calculate volume and other properties:
  (With no arguments given, a cylinder has a radius of 1 and a height of 2.)
  
   
   
    | Out[2]= |  | 
   
   
  You can also find formulas and other information using natural-language input:
  
    | Out[3]= |  |
