C program to enter two angles of a triangle and find the third angle.

In this tutorial you will learn about the C program to enter two angles of a triangle and find the third angle. and its application with practical example.

In this tutorial, we will learn to create a C program that will find side of a Triangle.If two side of a Triangle are given   using C programming.

Prerequisites

Before starting with this tutorial we assume that you are best aware of the following C programming topics:

  • Arithmetic operators
  • Data types
  • Basic input/output.

Basic Properties of triangle

The sum of the interior angle on the same vertex is 180°

 

C Program to enter two angles of a triangle and find the third angle.

Here we take two side of a triangle and with the help of angle property we will find the required third side of a triangle ,Let’s take a look to program.

output

the above program, we have first declared and initialized a set variables required in the program.

  • ang1 =it is for holding the angle value 1.
  • ang2 =it is for holding the angle value 2.
  • ang3 =it is for holding the angle value 3.

One of the common property of a triangles is that all three(3) interior angles (∠a + ∠b +∠c) of a triangle on adding will give to 180 degrees. This is an important theorem of geometry also known as Triangle Angle Sum Theorem(∠a + ∠b +∠c).According to this Theorem, the sum of the three interior angles in a triangle is always 180°.

So using this triangle  angle sum theorem we create a program in which we get two angle from user and by adding them subtract from 180 -(ang1+ang2) we will get our required third angle .

as we can see here by adding two given angle and subtract them from 180 we get the third required angle ..

 

In this tutorial we have learn about the C program to enter two angles of a triangle and find the third angle. and its application with practical example. I hope you will like this tutorial.
