Sepow means "Executioner's knife". It is the symbol of A symbol of justice.

We will use the 5 pixel grid to trace out this image. The image of this is shown below:

The plan to draw this shape is given below:

- Lift up the pen
- Set the pensize to 30 pixels
- Move the pen to the location of the leftmost part of the triangle
- Find the distance and the angle between the leftmost part and the topmost part
- Draw the triangle
- Draw the circle

__Using Turtle Graphics__

We will use the template.py file and rename it to sepow.py.

Steps 1 and 2 are simple, we only need to lift up the pen. The code to do this is shown below:

turtle.penup()

turtle.pensize(30)

The leftmost tip of the pen is at (-105, -20) to find the optimal position of the pen, we must add 15 pixels to it. This gives us: (-90, -5).

Compensating for the position of the pen, the coordinate of the topmost position is (0, 175).

The function to find the angle between the two points is given below:

def angleBetweenPoints(x1, y1, x2, y2):

myradians = math.atan2(y2 - y1, x2 - x1)

angle = math.degrees(myradians)

return angle

The function to find the distance between the two point is given below:

def coordinateDistance(x1, y1, x2, y2):

dx = x1 - x2

dy = y1 - y2

D = math.sqrt((dx * dx) + (dy * dy))

return D

To use the above functions, we use the code shown below:

angle = angleBetweenPoints(-90, -5, 0, 175)

length = coordinateDistance(-90, -5, 0, 175)

To draw the triangle, we use the code shown below:

turtle.setposition(-90, -5)

turtle.pendown()

turtle.setheading(angle)

turtle.forward(length)

turtle.setheading(360 - angle)

turtle.forward(length)

turtle.setheading(180)

length = coordinateDistance(-90, -5, 90, -5)

turtle.forward(length)

The generated image is shown below:

Drawing the circle is quite easy. We move the turtle to the position (85, -90) and draw a circle of radius 85 pixels.

The code to do this is shown below:

turtle.penup()

turtle.setposition(85, -90)

turtle.pendown()

turtle.setheading(90)

turtle.circle(85)

The generated image is shown below:

__Conclusion__

At the end of this section, we have successfully drawn the Sepow symbol.

This post is part of the series: Drawing Adinkra Symbols using Python. The goal is to draw 40 Adinkra symbols using the Python programming language.
