A two-dimensional closed geometric figure with at<br />
least one angle measuring 180° is concave.<br />
These figures are named according to the number<br />
of sides <strong>and</strong> vertices each has.<br />
Circumference can be calculated using the formula<br />
C = 2πr.<br />
A diameter is a chord that passes directly through<br />
this figure’s center.<br />
When these figures have sides that are all the same<br />
length <strong>and</strong> angles that are all the same size, they are<br />
called regular.<br />
