Which polygon has the most sides?

decagon
20-gon
nonagon
dodecagon

decagon = 10

nonagon = 9

dodecagon = 12

Step-by-step explanation:

decagon = a plane figure with ten straight sides and angles.

20-gon = In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon's interior angles is 3240 degrees.

nonagon = a plane figure with nine straight sides and nine angles.

dodecagon = a plane figure with twelve sides.

Step-by-step explanation:

the answer is c.

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.
