Work out the size of each interior angle in a regular polygon Tom and Katie are discussing how to calculate the size of each interior angle in a regular \( 20 \) sided shape

Tom says you can do \( \frac{18 \times 180}{20} \)

Katie says you can do \( 180-\frac{360}{20} \)

Who is correct? Only Katie

Believes the only way to find the interior angle of a regular polygon is to subtract the exterior angle from 180.
