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
,
  • 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

Bonus problem: Parallelogram on the coordinate plane

You are graphing quadrilateral A, B, C, D in the coordinate plane. The length of segment A, B is the same as the length of segment D, C, and both segments are horizontal. The following are three vertices of the quadrilateral: A, left parenthesis, 1, comma, 1, right parenthesis, C, left parenthesis, 4, point, 5, comma, 4, right parenthesis, and D, left parenthesis, minus, 1, point, 5, comma, 4, right parenthesis. All you know about point B is that it is in the first quadrant.
What are the coordinates of point B?
