Question

please look over my answers idk if I answered them right.
The figure shows triangle DEF and line segment BC, which is parallel to EF:

Triangle DEF has a point B on side DE and point C on side DF. The line BC is parallel to the line EF and correspond and are congruent to each other.

Part A: Is triangle DEF similar to triangle DBC? Explain using what you know about triangle similarity.
My answer- Yes, triangle DEF is similar to triangle DBC. 

Angle DEF is congruent to angle DBC because line segments BC and EF are parallel lines cut by a transversal DE. Corresponding angles DEF and DBC are congruent. 
Part B: Which line segment on triangle DBC corresponds to line segment EF? Explain your answer.
My answer- Line segment EF corresponds with line segment BC on triangle DBC. Line segment EF and BC are parallel lines and are congruent.
Part C: Which angle on triangle DBC corresponds to angle F? Explain your answer.
My answer- Angle F corresponds with angle C on triangle DBC. corresponding angles DCB and DFE are congruent because line segments BC and EF are parallel lines cut by a transversal DF.

Answer 1

um

Answer 2

just um think of an answer

Answer 3

like a first step please try draw this case

Answer 4

@jhonyy9 sorry i for got to add the image. I posted it now.

Answer 5

so your answers maybe correct just why or how you think that line segment EF and BC are congruent ? look please on this posted image - these line segments are parallel and proportional but congruent not can be
