8-119.

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

1. regular hexagon

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

2. regular decagon

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

3. equilateral triangle

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

4. square

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

• (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 $120^\circ$
