# C++ Program to Calculate Area of Right Angle Triangle

### Introduction:

In geometry, a triangle is a three-sided polygon with three angles. **Right angle triangle** is a special type of triangle which has one angle of 90 degrees. The area of a right angle triangle is half of the product of its base and height. In this article, we will discuss *how to calculate the area of a right angle triangle using C++ programming language*.

### Problem Statement:

Write a *C++ program to calculate the area of a right angle triangle*, given its base and height.

### Solution:

To *calculate the area of a right angle triangle* in C++, we need to take two inputs from the user: base and height. After that, we will use the formula for the** area of a right angle triangle**, which is half of the product of its base and height.

Let's see the code:

```
#include <iostream>
using namespace std;
int main()
{
float base, height, area;
cout << "Enter base and height of the triangle: ";
cin >> base >> height;
area = 0.5 * base * height;
cout << "Area of the triangle = " << area;
return 0;
}
```

**Explanation:**

In the above code, we have used the `iostream` library to include the `cout` and `cin` objects for input and output operations. We have also used the `using namespace std;` statement to avoid the prefix `std::` before the objects.

Then, we have declared three float variables `base`, `height`, and `area` to store the values of base, height, and area respectively.

Next, we have prompted the user to enter the base and height of the triangle using `cout` and read them from the keyboard using `cin`.

After that, we have used the formula for the area of a right angle triangle, which is half of the product of its base and height, and assigned the result to the `area` variable.

Finally, we have printed the value of the area of the triangle using `cout`.

**Testing:**

Let's test the program with some sample inputs.

**Test Case 1:**

Enter base and height of the triangle: 5 4

Area of the triangle = 10

**Test Case 2:**

Enter base and height of the triangle: 10 12

Area of the triangle = 60

**Test Case 3:**

Enter base and height of the triangle: 7.5 6.2

Area of the triangle = 23.25

All the test cases are working fine and giving the correct output.

### Conclusion:

In this article, we have discussed *how to calculate the area of a right angle triangle using C++ programming language*. We have used the formula for the *area of a right angle triangle*, which is half of the product of its base and height. We have also tested the program with some sample inputs and found that it is working fine.
