get-angle-type.js

// Implement a function getAngleType, and tests for each of the acceptance criteria.

// Acceptance criteria:

// Identify Right Angles:
// When the angle is exactly 90 degrees,
// Then the function should return "Right angle"

// Identify Acute Angles:
// When the angle is less than 90 degrees,
// Then the function should return "Acute angle"

// Identify Obtuse Angles:
// When the angle is greater than 90 degrees and less than 180 degrees,
// Then the function should return "Obtuse angle"

// Identify Straight Angles:
// When the angle is exactly 180 degrees,
// Then the function should return "Straight angle"

// Identify Reflex Angles:
// When the angle is greater than 180 degrees and less than 360 degrees,
// Then the function should return "Reflex angle"
