in c check if triangle is a right triangle

To check if a triangle is a right triangle in C, you can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Here are the steps to check if a triangle is a right triangle:

  1. Declare variables: Declare three variables to represent the lengths of the three sides of the triangle: side1, side2, and side3.

  2. Input side lengths: Use scanf or any other input method to get the lengths of the three sides from the user.

  3. Check the Pythagorean theorem: Use an if statement to check if the Pythagorean theorem holds true for the given side lengths. The condition for a right triangle is that the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.

c if ((side1 side1) == (side2 side2) + (side3 * side3) || (side2 side2) == (side1 side1) + (side3 * side3) || (side3 side3) == (side1 side1) + (side2 * side2)) { // The triangle is a right triangle printf("The triangle is a right triangle.\n"); } else { // The triangle is not a right triangle printf("The triangle is not a right triangle.\n"); }

This code checks if any of the three conditions of the Pythagorean theorem are satisfied. If any of the conditions are true, it means the triangle is a right triangle. Otherwise, it is not a right triangle.

  1. Output the result: Use printf or any other output method to display the result to the user.

That's it! The code will determine whether the triangle is a right triangle based on the input side lengths.

Please note that this code assumes the input side lengths are valid and non-zero. You may need to add additional input validation if necessary.
