Are the truss triangles ABD and BFC congruent? Which postulate did you use for your proof? Which engineer was correct? Engineer Natalie's statement is that ΔABD is congruent to ΔCBF by Side Angle Side rule of congruency

Engineer Emma's statement is that ΔABD is congruent to ΔCBF by Side Side Side rule of congruency

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
