Question

This question is from the textbook "Python for ArcGIS" by Laura Tateosian:

Write a script "triangles.py" that takes three arguments, the lengths of three sides of a triangle. Then define the following three functions:

1. perimeter takes three side lengths as arguments and returns the perimeter length.

2. triangleType takes three side lengths as arguments, determines if it is an equilateral triangle, an isosceles triangle, or neither. The result is returned.

3. area takes three side lengths as arguments and returns the area. Compute this as the square root of (p*(p-a)*(p-b)*(p-c)), where p is half the perimeter and a, b, and c are the side lengths. Use a math module function to compute the square root.

Call the functions and print the results as shown below:

Example input: 1 1 1

Example output:

>>> Triangle sides: 1.0, 1.0, 1.0

Perimeter = 3.0

Type = Equilateral

Area = 0.4330127

Answer 1

If you copy the code as it is do check that the indentation is proper import math #to use a math module function to compute the square root 

class triangle: #creating a class a = float(input()) #input for first side b = float(input()) #input for second side c = float(input()) #input for third side print('triangle sides = ',a,',',b,',',c) #to print the given sides   def perimeter(a,b,c): #creating perimeter function p = a+b+c #to calculate the perimeter print('perimeter = ',p) #to print the perimeter def area(a,b,c): #creating area function p = (a + b + c) / 2 #calculates the half of the perimeter area = (p * (p - a) * (p - b) * (p - c)) #calculating the area area = math.sqrt(area) #calculating the area print('area = ',area) #to print the area def type(a,b,c): #creating typ function if a == b == c: #condition to check for equilateral triangle print("Type = Equilateral triangle") #to print it is equilateral triangle elif a == b or b == c or c == a: #condition to check for isosceles triangle print("Type = isosceles triangle") #to print it is isosceles triangle else: print("Type = Scalene triangle") #to print it is scalene triangle perimeter(a,b,c) #calling perimeter function type(a,b,c) #calling type function area(a,b,c) #calling area function
