JavaScript: Find the types of a specified angle

JavaScript Basic: Exercise-86 with Solution

Find Type of Given Angle

Write a JavaScript program to find the types of a given angle.

Types of angles:
• Acute angle: An angle between 0 and 90 degrees.
• Right angle: An 90 degree angle.
• Obtuse angle: An angle between 90 and 180 degrees.
• Straight angle: A 180 degree angle.

Visual Presentation:

Sample Solution:

JavaScript Code:

 // Function to determine the type of angle based on its measure
function angle_Type(angle) {
  if(angle < 90) {
    return "Acute angle.";  // Return this message if the angle is less than 90 degrees
  }
  if(angle === 90) {
    return "Right angle.";  // Return this message if the angle is exactly 90 degrees
  }
  if(angle < 180) {
    return "Obtuse angle."; // Return this message if the angle is less than 180 degrees but not 90 degrees
  }
  return "Straight angle.";  // Return this message if the angle is exactly 180 degrees
}

// Example usage
console.log(angle_Type(47));   // Acute angle.
console.log(angle_Type(90));   // Right angle.
console.log(angle_Type(145));  // Obtuse angle.
console.log(angle_Type(180));  // Straight angle.

Output:

Acute angle.
Right angle.
Obtuse angle.
Straight angle.

ES6 Version:

// Function to determine the type of angle based on its measure
const angle_Type = (angle) => {
  if (angle < 90) {
    return "Acute angle."; // Return this message if the angle is less than 90 degrees
  }
  if (angle === 90) {
    return "Right angle."; // Return this message if the angle is exactly 90 degrees
  }
  if (angle < 180) {
    return "Obtuse angle."; // Return this message if the angle is less than 180 degrees but not 90 degrees
  }
  return "Straight angle."; // Return this message if the angle is exactly 180 degrees
};

// Example usage
console.log(angle_Type(47));   // Acute angle.
console.log(angle_Type(90));   // Right angle.
console.log(angle_Type(145));  // Obtuse angle.
console.log(angle_Type(180));  // Straight angle.

For more Practice: Solve these Related Problems:

• Write a JavaScript program that accepts an angle in degrees and categorizes it as acute, right, obtuse, or straight, ensuring valid input.
• Write a JavaScript function that determines the type of an angle based on its measure and returns a descriptive string.
• Write a JavaScript program that validates an angle’s value (0–180) and outputs its classification using conditional statements.
