I'm making a program where the user can click on the screen 3 times and it makes a triangle. It will then find the middle points of those 3 lines. Next, I want it to draw 3 lines perpendicular to each of the lines that make up the triangle (through the middle points).
I'm stuck at drawing the perpendicular lines. I wanted to try to save (like you save a position or coordinates) the angles that the turtle bob (the one that connects the lines of the triangle) makes on each line, and then put the middle line turtles (l1, l2, l3) tilt in that angle. It would then make it go right and left and draw the line. I'm sorry if this is unclear, but I can't really think of another way to explain it. This is my code:
import turtle
tur = turtle.Turtle() #draws the dots
bob = turtle.Turtle() #connects the dots
l1 = turtle.Turtle() #middle point of line 1
l2 = turtle.Turtle() #middle point of line 2
l3 = turtle.Turtle() #middle point of line 3
mid = turtle.Turtle() #point where the lines cross, haven't used this one yet
screen = turtle.Screen()
screen.tracer(0,0)
screen.setup(800,800)
tur.ht()
tur.up()
tur.speed(0)
bob.ht()
bob.up()
bob.speed(0)
screen.update()
l1.up()
l2.up()
l3.up()
mid.up()
mid.ht()
dots = 1
def lines():
line()
l1.goto(line_1_mid_cords) #go to middle of lines
l1.dot()
l2.goto(line_2_mid_cords)
l2.dot()
l3.goto(line_3_mid_cords)
l3.dot()
def line():
global line_1_mid_cords, line_2_mid_cords, line_3_mid_cords
line_1_mid_cords = (( bob_x1 + bob_x2 ) /2, ( bob_y1 + bob_y2 ) /2) #get middle coordinates
line_2_mid_cords = (( bob_x2 + bob_x3 ) /2, ( bob_y2 + bob_y3 ) /2)
line_3_mid_cords = (( bob_x1 + bob_x3 ) /2, ( bob_y1 + bob_y3 ) /2)
def dotOnClick(x,y):
global dots, bob_x1, bob_y1, bob_x2, bob_y2, bob_x3, bob_y3
if dots == 1:
if x >= -800 and x <= 800 and y >= -800 and y <= 800: #click on screen
tur.goto(x,y) #go to that point
bob.goto(tur.pos())#bob goes there too
bob_x1 = bob.xcor() #saves bobs coordinates
bob_y1 = bob.ycor()
tur.dot()
bob.down()
screen.update()
dots = 2
elif dots == 2:
if x >= -800 and x <= 800 and y >= -800 and y <= 800: #when second dot is clicked
tur.goto(x,y) #both tur and bob to to that point and they get connected
bob.goto(tur.pos())
bob_x2 = bob.xcor()
bob_y2 = bob.ycor()
tur.dot() #draws second dot
bob.down()
screen.update()
dots = 3
elif dots == 3:
if x >= -800 and x <= 800 and y >= -800 and y <= 800: #same for 3rd point on screen
tur.goto(x,y)
bob.goto(tur.pos())
bob_x3 = bob.xcor()
bob_y3 = bob.ycor()
tur.dot()
bob.down()
bob.goto(bob_x1,bob_y1) #bob goes to first dot and completes the triangle
lines() #makes the turtles l1, l2, l3 go to the middle points of the triangle lines
screen.update()
dots = 4
elif dots == 4:
if x >= -800 and x <= 800 and y >= -800 and y <= 800: #resets when you click again
tur.clear()
bob.clear()
screen.update()
tur.reset()
bob.reset()
tur.ht()
tur.up()
tur.speed(0)
bob.ht()
bob.up()
bob.speed(0)

dots = 1
turtle.onscreenclick(dotOnClick,1,True)
If I need to explain more about what I exactly mean, please say so!
