Read and plot first-quadrant coordinates, describe transformations and identify symmetry.
Example 1
A robot starts at A. It moves 3 squares east, 1 square west, then 1 squares north. What are its final coordinates?
First-quadrant coordinate gridShow worked answer
Answer: (8,4)
- Net horizontal move =3−1=2 right; vertical move =1 up.
- The final coordinate is (8,4).
Example 2
Which single transformation maps triangle ABC to its labelled image A′B′C′?
Triangle and imageShow worked answer
Answer: reflection
- Compare corresponding labelled corners. Translations slide, reflections flip and rotations turn.
- This is a reflection in the marked vertical mirror line; the size and shape remain unchanged.
Example 3
What are the coordinates of A? Enter x,y.

Answer: (4,4)
- Read horizontal position first (x), then vertical position (y).
- A=(4,4).
