Best ResponseYou've already chosen the best response.0I'm pretty sure I have gotten this down. 180°  84° = solution.

Best ResponseYou've already chosen the best response.2well the 2 curved arcs that make DGF also make DEF.. so I'd say the angles are equal... and in a kite those angles are equal...

Best ResponseYou've already chosen the best response.2oh and the triangle DGF is reflected in the line DF to form DEF...

Best ResponseYou've already chosen the best response.0With the answers provided, "none of the above" would be equal to 96°, yes?

Best ResponseYou've already chosen the best response.2but I don't think you need to prove congruency... just recognise the equal angle markings..
