Prove that the two triangles are congruent using the SAS congruence criteria. Show your work. Triangle DEF: D(3,2), E(5,3), F(4,5)

Triangle FGH: F(4,5), G(3,7), H(5,8)

Given: ∠DFE and ∠GFH are vertical angles

(4 points)

the correct is answer is a 9-sided polygon!

i think it is 18

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

your answer is  

a.
