Question

translate triangle A by vector (-3,1) to give triangle B. Then roste your triangle B 180 degrees around the origin to give triangle C. Describe fully the single transformation that maps triangle A onto triangle C

Answer 1

Answer:

From A to B.

The first transformation is a reflection across the x-axis, then a shift one unit down. Finally, a reflection acroos the line x = 1.5. These transformations give figure B.

From B to C.

To get figure C, we just need to do a 180° rotation across the origin. Or, you can see this transformation as a reflection acroos the origin, it would be the same result.
