Now rotate this right triangle 90 degrees about the
vertex point (2, 3). Explain how you know that you have
rotated the triangle 90 degrees.
т
Show and label the pre-image and the image after
the rotation in the "show your work" box.

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.

nope.   happens to me as well.
