If a shape is a regular hexagon with six sides, which of the following must be true? A. It has exactly one line of symmetry B. It has reflections symmetry C. It has six lines of symmetry D. It has an unlimited number of symmetry

is

A and D are correct

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
