If for $△\mathrm{ABC}$ and $△\mathrm{DEF}$, the correspondence $\mathrm{CAB}\leftrightarrow EDF$ gives a congruence, then which of the following is not true?

By which of the following criterion, congruence of the two triangles cannot be proved ?

In the adjoining figure, $\mathrm{ABC}$ is an isosceles triangle in which $\mathrm{AB}=\mathrm{AC}$. If $\mathrm{E}$ and $\mathrm{F}$ be the midpoints of $\mathrm{AC}$ and $\mathrm{AB}$ respectively, then

In the adjoining figure, $\mathrm{P}$ and $\mathrm{Q}$ and are two points on equal sides $\mathrm{AB}$ and $\mathrm{AC}$ of a isosceles triangle $\mathrm{ABC}$ such that $\mathrm{AP}=\mathrm{AQ}$, then

In the given figure, $\mathrm{ACE}$ and $\mathrm{ABD}$ are straight lines and $\mathrm{ABC}$ is an isosceles triangle in which $\mathrm{AB}=\mathrm{AC}$ . If $\mathrm{BD}=\mathrm{CE}$, then

If $\mathrm{△}\mathrm{ACB}\cong \mathrm{△}\mathrm{DFE}$, then find the measure of $\mathrm{\angle }\mathrm{F}$.

If $\mathrm{ABCD}$ is a square; $\mathrm{X}$ is the mid point of $\mathrm{AB}$ and $\mathrm{Y}$ is the mid point of $\mathrm{BC}$, then which of the following is not correct?

In the given figure, $\mathrm{△}\mathrm{ABO}$ and $\mathrm{△}\mathrm{CDO}$ are congruent. The value of $\mathrm{x}$ and $\mathrm{y}$ are
