**Coterminal Angles Explanation**

**Problem Statement:**
The angle between \(0^\circ\) and \(360^\circ\) that is coterminal with the \(688^\circ\) angle is _____ degrees.

**Solution:**

Coterminal angles are angles that share the same initial and terminal sides but may differ by an integer multiple of a full rotation (360°). To find a coterminal angle between 0° and 360° for an angle given in degrees, follow these steps:

1. **Determine the equivalent angle** by subtracting 360° from the given angle until the result is within the desired range (0° to 360°).

   \[
   688^\circ - 360^\circ = 328^\circ
   \]

Since \(328^\circ\) is between 0° and 360°, it is the coterminal angle within this range.

**Answer:**
The angle between \(0^\circ\) and \(360^\circ\) that is coterminal with the \(688^\circ\) angle is \(328^\circ\).

**Educational Insight:**
Understanding coterminal angles is crucial in various fields of mathematics, particularly in trigonometry and geometry. It helps in simplifying the study of periodic functions and rotational movements by providing a standard range for angle measurements.
