Question

Write a program that takes as input an x,y center value and radii for two circles, draws them in a turtle window, and prints whether they intersect or not. Submit the source code and two screen shots as the answer.

One screenshot should show intersecting circles, and one should show non-intersecting circles.

Answer 1

#sample outputs

from turtle import *

tobj = Turtle()

#get circles information from user

print("Circle 1");

c1x = int(input("Enter x coordinate:"))

c1y = int(input("Enter y coordinate:"))

r1 = int(input("Enter radius:"))

print("Circle 2");

c2x = int(input("Enter x coordinate:"))

c2y = int(input("Enter y coordinate:"))

r2 = int(input("Enter radius:"))

#draw circles

tobj.penup()

tobj.setposition(c1x,c1y)

tobj.pendown()

tobj.circle(r1)

tobj.penup()

tobj.setposition(c2x,c2y)

tobj.pendown()

tobj.circle(r2)

#intersection formula

dsq = (c1x - c2x) * (c1x - c2x) + (c1y - c2y) * (c1y - c2y)

rsq = (r1 + r2) * (r1 + r2)

if (dsq < rsq):

print("Circles intersect")

else:

print("Circles Does not intersect")
