Part 2: Polygons on the Coordinate Plane GNB pg. 134-136

Points J and K, plotted on the coordinate grid, are two vertices of rectangle JKLM. Rectangle JKLM has an area of 14 square units. Point J is located at (2,1), and point K is located at (-5, 1). Each vertex of the rectangle is located at a point that has integer coordinates. Part A: Which points could be another vertex of a rectangle?

Choose four. Remember, you can make a rectangle going up or down. (Two separate rectangles with an area of 21)

Points J and K, plotted on the coordinate grid, are two vertices of rectangle JKLM. Rectangle JKLM has an area of 21 square units. Point J is located at (2,1), and point K is located at (-5, 1). Each vertex of the rectangle is located at a point that has integer coordinates.

Part B: What is the perimeter of one of the rectangles with an area of 21?

The perimeter is _______ units.

Page 136 Question 1:

You want to draw a 6-by-5 rectangle with vertices at (-2.5, 2) and (3.5, -3). Find the coordinates of the two missing vertices.

What are the coordinates of the missing vertices?

Page 136 Question 3:

You and your friend are each drawing a 2.5 by 6.1 rectangle with vertices (4.5, 7.1) and (2,1). Your friend says that the coordinates of the missing vertices are (1, 4.5) and (7.1, 2). What are the coordinates?

The correct missing vertices are (4.5, ​ (a)   ) and (2, ​ (b)   )

With the two known vertices (1.7, 3.6) and (4.3, 6.4), which x-coordinates do you need to use for the two missing vertices to make a rectangle?

What is an integer?

When graphing points in the coordinate plane. You first start at the origin, (0,0). Then use the x-coordinate to move __________________.
