Verified working — step 1
A translation vector reads top-then-bottom: the top number moves x (right for positive), the bottom moves y (DOWN for negative). Move one vertex, then slide the whole triangle rigidly.The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
