Is it possible to create a regular tessellation using a regular decagon? Explain. Yes, 2 decagons with a common vertex will have
interior angle measures that sum to 360. Yes, 3 decagons with a common vertex will have interior angle measures that sum to 360. Yes, all of the angles and sides of each decagon are congruent. No, a tessellation of 2 decagons will have a gap, and a tessellation of 3 decagons will overlap.
