Question

1. find the last vertex of a square whose three vertices are (7,3), (7,9), (1,9). type a response

Explanation:

Step1: Identify vertical side

Points (7,3) and (7,9) have same x-coordinate, so vertical side length is $9-3=6$.

Step2: Identify horizontal side

Points (7,9) and (1,9) have same y-coordinate, so horizontal side length is $7-1=6$.

Step3: Find missing vertex

The missing vertex shares x=1 (from (1,9)) and y=3 (from (7,3)), so it is (1,3).

Answer:

(1,3)
