Triangle END is reflected across the line y = x using the rule (x, y) - (,x) to create triangle E'N'D'. If a line segment is drawn from point E to point E', which statement would best describe the line segment drawn in relation to the line y = x?
Both are congruent to each other.
Both create diameters of concentric circles.
They are parallel.
They are perpendicular

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. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
