Atriangle, △abc, is rotated 90° counterclockwise, reflected across the x−axis, and then reflected across the y−axis. select true or false for each statement. -rotating △abc 180° clockwise is an equivalent transformation. -rotating △abc 270° clockwise is an equivalent transformation. -reflecting △abc across the y-axis is an equivalent transformation.

false, true, true

Step-by-step explanation:

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.
