Aim:
Write a program to compute distance between two points taking input from the user (Pythagorean Theorem).
Description:
The Pythagorean theorem is the basis for computing distance between two points. Let
(x1,y1) and (x2,y2) be the co-ordinates of points on xy-plane. From Pythagorean theorem, the
distance between two points is calculated using the formulae:
To find the distance, we need to use the method sqrt(). This method is not accessible
directly, so we need to import math module and then we need to call this method using math static
object.
To find the power of a number, we need to use ** operator.
Algorithm:
Input: x1,y1,x2 and y2
Output: Distance between two points.
Step1: Start
Step2: Import math module
Step3: Read the values of x1,y1,x2 and y2
Step4: Calculate the distance using the formulae math.sqrt( (x2 - x1)**2 + (y2 - y1)**2 ) and store
the result in distance
Step5: Print distance
Step6: Stop.
Program:
import math
x1=int(input("Enter number:"))
x2=int(input("Enter number:"))
y1=int(input("Enter number:"))
y2=int(input("Enter number:"))
distance=math.sqrt((x2-x1)**2+(y2-y1)**2)
print("Distance between two points is : ",distance)
OR
import math;
x1=int(input("Enter x1--->"))
y1=int(input("Enter y1--->"))
x2=int(input("Enter x2--->"))
y2=int(input("Enter y2--->"))
d1 = (x2 - x1) * (x2 - x1);
d2 = (y2 - y1) * (y2 - y1);
res = math.sqrt(d1+d2)
print ("Distance between two points:",res);
x1=int(input("Enter x1--->"))
y1=int(input("Enter y1--->"))
x2=int(input("Enter x2--->"))
y2=int(input("Enter y2--->"))
d1 = (x2 - x1) * (x2 - x1);
d2 = (y2 - y1) * (y2 - y1);
res = math.sqrt(d1+d2)
print ("Distance between two points:",res);
Output:
