Quadrilateral problems on the coordinate plane

Try five problems involving quadrilaterals on the coordinate plane.

Problem 1: Find coordinates of missing vertex

The coordinates of three of the vertices of rectangle A, B, C, D are A, left parenthesis, 2, comma, 1, right parenthesis, comma, B, left parenthesis, 5, comma, 1, right parenthesis, comma and C, left parenthesis, 5, comma, 6, right parenthesis.
What are the coordinates of point D?
left parenthesis
  • Your answer should be
  • an integer, like 6
  • an exact decimal, like 0, point, 75
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
