The table contains the proof of the theorem of the relationship between slopes of parallel lines. what is the missing statement in step 2?
bc = ef, ab = de
bc × ab = -(ef × de)

Using the following statements will help you get a better understanding of these congruent triangles. Triangle ABC and DEF are similar. Similar triangles. Slope of line AC = BC/AB. Slope of line DF = EF/DE. Slope of line AC = Slope of line DF.

I think the answer is choice A). BC/AB = DE/EF

I hope this helps xx

i think the answer could be

A). BC/AB = DE/EF

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
