- A(0, 3)
- B(3, 0)
- C(0, 6)
- D(6, 6)
Step-by-Step Solution
For a rectangle with A(0,0), B(6,0), C(6,3), the fourth vertex D lies above A at (0, 3), so AD is parallel to BC.
Answer: A) (0, 3)
Three vertices of a rectangle are A(0, 0), B(6, 0) and C(6, 3). Which of the following is the correct fourth vertex D?

Key idea: Reading coordinates
Given a point on a graph:
1. Drop a perpendicular to the -axis. Where it hits is the -coordinate.
2. Drop a perpendicular to the -axis. Where it hits is the -coordinate.
3. Combine: .
Reverse if you're given coordinates: read first (horizontal direction), then (vertical direction). Don't swap their roles.
