Polygon TRIG is a quadrilateral. Which of the following pieces of information would prove that TRIG is a parallelogram

step-by-step explanation:

i am not sure sorry : c

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1

you are having disney spells!
