Write a Python Program to Calculate the Area of a Triangle

program calculates the area of an Equilateral Triangle

Area of an Equilateral Triangle

An equilateral triangle is a triangle where all the sides are equal. The perpendicular drawn from the vertex of the triangle to the base divides the base into two equal parts. To calculate the area of the equilateral triangle, we have to know the measurement of its sides.

Area of an Equilateral Triangle = A = (√3)/4 × side2

Python Program:

# import the math module
import math

side=int(input("enter the side of the triangle:"))
area=math.sqrt(3)/4*(side*side)
print("the area of this equaliteral triangle is : ",area)
print("the area of this equaliteral triangle after rounding is : ",round(area,0))

base=int(input("enter the base of the triangle:"))
height=int(input("enter the height of the triangle:"))
area=(base*height)*0.5
print("the area of the triangle of base:",base," and height:",height," is : ",area)

side1 = int(input('enter side1:'))
side2 = int(input('enter side2:'))
side3 = int(input('enter side3:'))
s = (side1 + side2 + side3) / 2;
area = (s * (s - side1) * (s - side2) * (s - side3))**0.5
print("The area of the triangle is " , area);
