Wendy described four triangles as shown below:
triangle a: all sides have length 9 cm.
triangle b: two sides have length 10 cm, and the included angle measures 60°. triangle c: two angles measure 50°.
triangle d: base has length 8 cm, and base angles measure 45°.

which triangle is not a unique triangle?

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
