Question

two rigid transformations are used to map \\( \triangle hjk \\) to \\( \triangle lmn \\). the first is a translation of vertex \\( h \\) to vertex \\( l \\). what is the second transformation? a rotation about point \\( k \\) a reflection across the line containing \\( hj \\) a reflection across the line containing \\( hk \\) a rotation about point \\( h \\)

Explanation:

Step1: Analyze the transformation after translation

After translating vertex \(H\) to vertex \(L\), we need to make the two triangles coincide.

Step2: Check the orientation

Looking at the triangles \(\triangle HJK\) and \(\triangle LMN\), a rotation about point \(H\) (which is now at \(L\) after translation) can align the two triangles.

Answer:

a rotation about point \(H\)
