1. The formula for the measure of each interior angle of a regular $$ n $$-gon is:
   $$
   \text{Interior angle} = \frac{(n-2) \times 180^\circ}{n}
   $$

2. For $$ n = 90 $$:
   $$
   \text{Interior angle} = \frac{(90-2) \times 180^\circ}{90} = \frac{88 \times 180^\circ}{90}
   $$

3. Simplify the expression:
   $$
   \frac{88 \times 180^\circ}{90} = 88 \times \left(\frac{180^\circ}{90}\right) = 88 \times 2^\circ = 176^\circ
   $$

4. The measure of each exterior angle of a regular $$ n $$-gon is given by:
   $$
   \text{Exterior angle} = \frac{360^\circ}{n}
   $$

5. For $$ n = 90 $$:
   $$
   \text{Exterior angle} = \frac{360^\circ}{90} = 4^\circ
   $$

The measure of each interior angle is $$176^\circ$$, and the measure of each exterior angle is $$4^\circ$$.
Each interior angle is $$176^\circ$$ and each exterior angle is $$4^\circ$$.
