+# GetLocalEulerAngles
+
+Get the local rotation as Euler angles in degrees.
+
+## Syntax
+
+```cpp
+Math::Vector3 GetLocalEulerAngles() const;
+```
+
+## Returns
+
+Returns the local rotation as Euler angles `(x, y, z)` in degrees.
+
+## Remarks
+
+Converts the local quaternion rotation to Euler angles representation. The angles represent rotation around the X, Y, and Z axes respectively.

+## Examples
+
+```cpp
+void Example(TransformComponent* transform) {
+    Math::Vector3 eulers = transform->GetLocalEulerAngles();
+    XC_LOG_INFO("Local euler angles: ({}, {}, {})", eulers.x, eulers.y, eulers.z);
+}
