Given that these shapes are congruent, find the values of $x$x and $y$y.
Given that $\triangle BAC\equiv\triangle FED$△BAC≡△FED, which angle of $\triangle FED$△FED corresponds to $\angle ABC$∠ABC?
Given that $\triangle QPO\equiv\triangle CBA$△QPO≡△CBA, which angle of $\triangle QPO$△QPO corresponds to $\angle BCA$∠BCA?
The two given triangles are congruent. By considering the relative position of angles and sides, or otherwise, find the missing values. Give a reason for each answer.
