Measure of a Regular 16-gon (Hexadecagon) - A regular 16-gon has 16 equal sides and 16 equal angles.- The measure of each interior angle is given by the formula:\text{Interior Angle} = \frac{(n - 2) \times 180^\circ}{n} where n = 16 .- Calculate:\frac{(16 - 2) \times 180^\circ}{16} = \frac{14 \times 180^\circ}{16} = \frac{2520^\circ}{16} = 157.5^\circ- Therefore, each interior angle of a regular 16-gon measures 157.5 degrees.- The sum of all interior angles is:(n - 2) \times 180^\circ = 14 \times 180^\circ = 2520^\circ
