Triangle ABC has vertices A(1, 1), B(4, 1) and C(1, 5). It is reflected in the y-axis to triangle A'B'C'. Write the coordinates of the image and state whether the area changes.
Reflection
Original Khojo Papers practice question — not from a past board paper.
B(2, −3), C(−2, −3), and the single transformation is a reflection in the origin.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Reflecting in the x-axis and then in the y-axis changes the sign of both coordinates, which is exactly reflection in the origin.
