Applying Properties of Congruence Triangle

Which of the following cannot be used to prove that two triangles are congruent?

What triangle congruence is shown in the figure?

Given that ∠BEA dfc are right angles and ae gcf what theorem or postulate guarantees that ∆AEB≅∆CFD?

$$∠BEA\ and\ ∠DFC$$  are right angles. To establish congruence between $$∆EBC\ and\ ∆FDA$$   using HA Theorem, which pair of corresponding parts do you need to show as congruent?

Given that $$∠BEA\ and\ ∠DFC$$  are right angles. What postulate guarantees that $$∆BAC≅∆DCA$$  ?

$$∠BEA\ and\ ∠DFC$$  are right angles. Which pair of corresponding parts do you still need to show as congruent to establish congruent between $$∆BEA≅∆DFC$$  using AAS Postulate?

Given that ∠BEA and ∠DFC are right angles. Suppose that ∆AFD≅∆CEB, which statement justifies that overline{AF}≅overline{CE}?

The figure below shows ΔABC $$\cong$$   ΔDEF, what is the value of x?

Which postulate can be used to prove the triangles congruent?

Given the figure below, what is the length of side BC?
