// Implement a function getAngleType
//
// When given an angle in degrees, it should return a string indicating the type of angle:
// - "Acute angle" for angles greater than 0° and less than 90°
// - "Right angle" for exactly 90°
// - "Obtuse angle" for angles greater than 90° and less than 180°
// - "Straight angle" for exactly 180°
// - "Reflex angle" for angles greater than 180° and less than 360°
// - "Invalid angle" for angles outside the valid range.

// Assumption: The parameter is a valid number. (You do not need to handle non-numeric inputs.)

// Acceptance criteria:
// After you have implemented the function, write tests to cover all the cases, and
// execute the code to ensure all tests pass.
