# Python Program to Calculate the Area of a Right Angled Triangle

###### Tutorialsrack 12/05/2020 Python

In this python program, we will learn how to calculate the area of a right-angled triangle.

## What is a Right Angled Triangle?

A right triangle or right-angled triangle is a triangle in which one angle is a right angle. In other words, we can say that the right angle triangle is a triangle in which one angle is a 90o angle. The relation between the sides and angles of a right triangle is the basis for trigonometry. The side opposite the right angle is called the hypotenuse. The sides adjacent to the right angle are called legs.

## Formula

Here is the source code of the program to calculate the area of a right-angled triangle.

##### Python Program to Calculate the Area of a Right Angled Triangle
``````# Python Program to Calculate the Area of a Right Angled Triangle

# Area = 1/2*width*height

# Import Module
import math

# Take the Input From the User
width = float(input("Enter the Width of a Right Angled Triangle: "))
height = float(input("Enter the Height of a Right Angled Triangle: "))

# Calculate the Area
Area = 0.5 * width * height

# Calculate the Third Side
c = math.sqrt((width*width) + (height*height))

# Calculate the Perimeter
Perimeter = width + height + c

# Print the output
print("\nArea of a right angled triangle is: %.2f" %Area)
print("Other side of right angled triangle is: %.2f" %c)
print("Perimeter of right angled triangle is: %.2f" %Perimeter)
``````

##### Output

Enter the Width of a Right Angled Triangle: 5

Enter the Height of a Right Angled Triangle: 6

Area of a right angled triangle is: 15.00

Other side of right angled triangle is: 7.81

Perimeter of right angled triangle is: 18.81
