Example of Math Operations in Logo Programming Language

example of how math operations can be used in the Logo Programming Language to create a geometric design. In this example, we’ll draw a regular polygon (a pentagon) and calculate its properties.

Step 1: Setup the Environment

First, let’s make sure our environment is ready for drawing. We need to ensure the turtle is positioned correctly and the canvas is clear.

cs                  ; Clear the screen
home                ; Move the turtle to the center of the screen

Step 2: Define Basic Arithmetic Operations

We’ll use basic arithmetic operations to calculate the necessary properties for our polygon.

  • Number of sides: 5 (for a pentagon)
  • Length of each side: 50 units
  • Interior angle: (180 – (360 / 5)) degrees
make "sides 5
make "length 50
make "angle (180 - (360 / :sides))

Step 3: Draw the Pentagon

Using a loop, we can draw each side of the pentagon by moving the turtle forward and turning it by the calculated angle.

repeat :sides [
    forward :length
    right 360 / :sides
]

Step 4: Calculate Perimeter and Area

Next, we’ll calculate the perimeter and area of the pentagon using math operations.

  • Perimeter: sides * length
  • Area: (sides * length^2) / (4 * tan(pi / sides))
make "perimeter (product :sides :length)
make "area (quotient (product :sides (power :length 2)) (product 4 (tan (quotient pi :sides))))
print (sentence [Perimeter:] :perimeter)
print (sentence [Area:] :area)

Full Code Example

Here’s the complete code that combines all the steps:

cs                      ; Clear the screen
home                    ; Move the turtle to the center of the screen

make "sides 5           ; Number of sides for the pentagon
make "length 50         ; Length of each side
make "angle (180 - (360 / :sides))  ; Interior angle

repeat :sides [         ; Draw the pentagon
    forward :length
    right 360 / :sides
]

make "perimeter (product :sides :length)  ; Calculate perimeter
make "area (quotient (product :sides (power :length 2)) (product 4 (tan (quotient pi :sides))))  ; Calculate area

print (sentence [Perimeter:] :perimeter)  ; Print perimeter
print (sentence [Area:] :area)            ; Print area
