Question

is \\( \triangle mno \\) congruent to \\( \triangle vwx \\)? justify your answer using rigid motions.

yes. a dilation and a reflection can map \\( \triangle mno \\) onto \\( \triangle vwx \\).

yes. a translation and a rotation can map \\( \triangle mno \\) onto \\( \triangle vwx \\).

no. it is not possible to map \\( \triangle mno \\) onto \\( \triangle vwx \\) using only rigid motions.

Explanation:

First, check the angles of both right triangles. For $\triangle MNO$ (right-angled at $N$), the angles are $35^\circ$, $90^\circ$, and $55^\circ$. For $\triangle VWX$ (right-angled at $W$), the angles are $30^\circ$, $90^\circ$, and $60^\circ$. Congruent triangles must have identical corresponding angles, but these triangles have different angle measures. Rigid motions (translation, rotation, reflection) preserve angle measures, so they cannot map a triangle with $35^\circ/55^\circ$ angles onto one with $30^\circ/60^\circ$ angles.

Answer:

No. It is not possible to map $\Delta MNO$ onto $\Delta VWX$ using only rigid motions.
