# The sum of the interior angle measures of an n-sided, convex polygon is <math>(n-2).180</math>

# The sum of the interior angle measures of an n-sided, convex polygon is <math>(n-2).180</math>

# Each exterior angle must be <math>360/n</math>

# Each exterior angle must be <math>360/n</math>

# Each of the exterior angle and interior angles are measured from the same line. hence they add upto 180 degrees.
