Simplify the expression

How does reflecting or rotating a figure change the interior angles of the figure?

Find an bif a = {3, 6, 9, 12) and b = {2, 4, 6, 8, 10).

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
