Question

This diagram shows triangles ABC and PQR.
ABC is mapped to PQR by combining two single transformations
The first is a rotation of 90 degrees clockwise about C
Describe fully the second transformation

Answer 1

Answer:

A reflection across the line x=3, a reflection across the x-axis and a dilation with a scale factor of 2, because each side is double.

Step-by-step explanation:

We know that the first transfomration is a rotation 90° clockwise.

Notice that vertex R is at the same horizontal coordinate than vertex C, which means the second transformation must include a reflection across the line x=3, a reflection across the x-axis and a dilation with a scale factor of 2, because each side is double.
