'run' is distance x direction changes

'rise' is distance y direction changes

slope='rise'/'run'

for ABC

'run' is 11-3 or 8

'rise' is 10-0=10

slope=10/8=5/4=1.25 (dunno if your program wants fraction or decimal)

for DEF

'run' is 19-15=4

'rise'=20-15=5

slope=5/4=1.25

they are equal because the 2 triangles are similar (congruent means exactly the same but they are different sizes)

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.
