Question

1. complete the square with vertices (3,7), (8,7), (3,12). (8,7) (8,12) (3,12) (7,12)

Explanation:

Step1: Identify given vertices

Given vertices: $(3,7)$, $(8,7)$, $(3,12)$

Step2: Find side length

Distance between $(3,7)$ and $(8,7)$: $8-3=5$
Distance between $(3,7)$ and $(3,12)$: $12-7=5$

Step3: Determine missing vertex

The missing vertex shares the x-coordinate of $(8,7)$ and y-coordinate of $(3,12)$: $(8,12)$

Answer:

(8,12)
