Question

Two rigid transformations are used to map ΔABC to ΔXYZ. The first is a translation of vertex A to vertex X. What is the second transformation?
a reflection across the line containing AB
a reflection across the line containing AC
a rotation about point A
a rotation about point B

Answer 1

Answer:

A. a reflection across the line containing AB

Step-by-step explanation:

We are given that,

There are two triangles ΔABC and ΔXYZ mapped onto each other.

It is given that, the the vertex A is shifted to the vertex X initially.

Now, we can see that,

To map ΔABC to ΔXYZ, the triangle ABC is reflected about the line AB.

Hence, option A i.e. a reflection across the line containing AB is correct.
