#### The points (6, 2), (3, -1) and (-2, 4) are the vertices of a right-angled triangle. Check whether it remains a right-angled triangle after reflection in the y-axis.

**Solution:**

#### The triangle ABC where A (1, 2), B (4, 8), C (6, 8) is reflected in the x-axis to triangle A’ B’ C’. The triangle A’ B’ C’ is then reflected in. The origin to triangle A”B”C” Write down the coordinates of A”, B”, C”. Write down a single transformation that maps ABC onto A” B” C”.

**Solution:**

#### The image of a point P on reflection in a line l is point P’. Describe the location of the line l.
