How do you find the measures of interior angles on a pentagon?
\n" ); document.write( "---
\n" ); document.write( "If it's a regular pentagon,
\n" ); document.write( "there are 5 exterior angles.
\n" ); document.write( "---
\n" ); document.write( "Sum of those angles is 360
\n" ); document.write( "---
\n" ); document.write( "Each ext. angle is 360/5 = 72 degrees.
\n" ); document.write( "====
\n" ); document.write( "So, each interior angle is 180-72 = 108 degrees.
\n" ); document.write( "=============================
\n" ); document.write( "Another way to do it.
\n" ); document.write( "Sum of the interior angles is (n-2)180 = 3*180 = 540
\n" ); document.write( "Then 540/5 = 108 degrees.
\n" ); document.write( "==============================
