Match each regular polygon named on the left with a statement about its qualities listed on the right.

1. regular hexagon

2. regular decagon

3. equilateral triangle

4. square

(1)  Central angle of $36^\circ$

(2)  Exterior angle measure of $90^\circ$

(4)  Exterior angle measure of $120^\circ$

(3)  Interior angle measure of $120^\circ$

Interior angle $= \frac{180^\circ(n - 2)}{n} = \frac{180^\circ(6 - 2)}{6}$

Central angle $= \frac{360^\circ}{10}$

Exterior angle $= \frac{360^\circ}{3}$

Exterior angle $= \frac{360^\circ}{4}$
