Write a program in C that displays the type of a triangle.

 /*This program is to find the type of the triangle according to user's input*/

#include <stdio.h>

printf("Enter the sides of the triangle: ");

scanf("%f %f %f", &side1, &side2, &side3);

printf("Enter the angles of the triangle: ");

scanf("%f %f %f", &angle1, &angle2, &angle3);


/*base of angles*/

if (angle1 && angle2 && angle3)

{

strcat(typeOfTri, " Right");
