Figure A is congruent to figure B. Which transformations are applied to figure A to obtain figure B?

O a reflection across the y-axis and then a translation down

O a rotation about the origin and then a reflection across the y-axis

O a rotation about the origin and then a translation down

O a reflection across the y-axis and then a reflection across the x-axis

Pls help

First option is the most suitable option, which says that a reflection of triangle A is made across the y - axis and then it is dragged down .

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.
