So the sum of other two sides must be greater than 50. Note: Result of output 4 gives “Invalid Triangle” because – the largest side is 50. Output 4: Enter values for a, b and c 10 50 20 Invalid Triangle Output 3: Enter values for a, b and c 10 50 50 It’s an Isosceles Triangle Output 2: Enter values for a, b and c 30 30 30 It’s an Equilateral Triangle Output 1: Enter values for a, b and c 4 5 6 It’s a Scalene Triangle Each triangle is different from the other on the basis of its unique properties. C Program To Check whether a Triangle is Equilateral, Isosceles or Scalene: Valid Triangle #include The three common types of triangles are scalene, equilateral, and isosceles triangles.
An equilateral triangle has all three sides equal in length. You can find the logic to it at Triangle Valid or Not based On Sides: C Program. Some examples are equilateral triangles, isosceles triangles and scalene triangles. We’ll need to write the C program to check if the entered values form a valid Triangle or not. YouTube Link: įirst we ask the user to input lengths of 3 sides of the Triangle. If above two conditions are false, then length of all sides of the Triangle is different or not equal, so it’s a Scalene Triangle.Ĭ Program To Check whether a Triangle is Equilateral, Isosceles or Scalene If any of these conditions are true, then 2 sides of the Triangle are equal. Next, if the first condition is false – we check if either length of a is equal to length of b or length of a is equal to length of c or length of b is equal to length of c.
Isoceles triangle is superset of Equilateral traingle. Scalene triangle is superset of isoceles triangle and equilateral triangle. If that’s true, then its Equilateral Triangle. Every equilateral is also an isoceles and scalene triangle. When all the three sides of the triangle are of different measures, it is a scalene triangle. When any two sides of the triangle are equal in length, it is an isosceles triangle. First we check if length of a is equal to length of b and length of c. Equilateral Triangle: Isosceles Triangle: Scalene Triangle: When all the three sides of the triangles are equal in length, it is an equilateral triangle. Based on sides, triangles are divided in three parts: 1) Equilateral triangle: which has all sides of equal length, 2) Isosceles triangle : which has two sides of equal length and 3) Scalene triangle: where each side of the triangle is different in length. Here a, b and c are lengths of sides of the triangle. Output 3: Enter values for a, b and c 10 15 8 It’s a Scalene Triangle Output 2: Enter values for a, b and c 20 20 30 It’s an Isosceles Triangle Output 1: Enter values for a, b and c 10 10 10 It’s an Equilateral Triangle Printf("It's an Equilateral Triangle\n") C Program To Check whether a Triangle is Equilateral, Isosceles or Scalene: Valid TriangleĬ Program To Check whether a Triangle is Equilateral, Isosceles or Scalene #include.C Program To Check whether a Triangle is Equilateral, Isosceles or Scalene.
