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.

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
