<P> A regular octagon is a closed figure with sides of the same length and internal angles of the same size . It has eight lines of reflective symmetry and rotational symmetry of order 8 . A regular octagon is represented by the Schläfli symbol ( 8 ) . The internal angle at each vertex of a regular octagon is 135 ° ( 3 π 4 ( \ displaystyle \ scriptstyle ( \ frac ( 3 \ pi ) ( 4 ) ) ) radians ) . The central angle is 45 ° ( π 4 ( \ displaystyle \ scriptstyle ( \ frac ( \ pi ) ( 4 ) ) ) radians ) . </P>
