Which of the following polygons can form a regular tessellation?

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

if i put something wrong your not gonna like it so rather not say nothing.

6(h+1)/2=a

a=area

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
