Example Question #1 : How To Find A Square On A Coordinate Plane

A coordinate plane is shown.

Blank_grid

Ralph plotted the following points on the coordinate grid:

Point W (3, 3); Point X (3, 8); Point Y (8, 3); Point Z (8, 8)

A polygon is formed with vertices W, X, Y, and Z. Which type of polygon is formed? 

Possible Answers:

Triangle

Square

Pentagon

Trapezoid

Correct answer:

Square

Explanation:

Start by plotting and connecting the vertices to create a quadrilateral.

The figure that is created has 4 right angles and sides of equal length. The only answer choice that shares these characteristics is the square.

Example Question #1 : Coordinate Geometry

Grid1st4

 

Renee plotted the following points in quadrant one on the coordinate grid:

Point A = (2,2)

Point B = (7,2)

Point C= (7,7)

Where in Quadrant one of the coordinate grid would Renee have to plot Point D so that the points form a square with vertices A, B, C, and D, and forms sides AB, BC, CD, and DA?

Possible Answers:

Correct answer:

Explanation:

Once Points A,B, and C have been plotted the missing coordinates in order to form a square (all sides being equal), Point D would be (2,7). All coordinates (x,y) in Quadrant one will be positive integers.

Another approach is to calculate the distance between each point.

When Point A and Point B are plotted they form a horizontal line that goes from 2 to 7. That makes the distance .

When Point B and Point C are plotted they form a vertical line that goes from 2 to 7. That makes the distance .

Point C creates a vertical line with Point B.  That makes the distance .

From here, we want to find a point that is horizontally 5 units from Point C and vertically 5 units from Point A. Thus (2,7) is the correct answer.

Example Question #1 : How To Find A Square On A Coordinate Plane

A square is plotted on a coordinate plane.  It includes the following points:   What is the remaining point?

Possible Answers:

Correct answer:

Explanation:

Each of the points is written as an ordered pair.  The first number in each ordered pair shows where the point is located on the x-axis.  The second number in each ordered pair shows where the point is located on the y-axis.  If you plot the ordered pairs listed in the problem, the ordered pair that is needed to complete the points of a square is .

Example Question #1 : How To Find The Points On A Coordinate Plane

In which quadrant is the point \dpi{100} (5,-6) located in? 

Possible Answers:

\dpi{100} I

\dpi{100} II

\dpi{100} IV

\dpi{100} III

Correct answer:

\dpi{100} IV

Explanation:

From the origin \dpi{100} (5,-6) is to the right 5 and down 6 making it in quadrant IV.

Example Question #2 : How To Find The Points On A Coordinate Plane

Angela plotted points A through E on the coordinate plane shown below.

 

Points_grid

What are the coordinates for point B?

Possible Answers:

(2, 7)

(7, 2)

(8, 8)

(8, 2)

(2, 8)

Correct answer:

(2, 8)

Explanation:

Begin at point (0, 0) in the bottom left hand corner of the coordinate plane. From there, count the number of spaces you move to the right to line up with Point B. This will be the first number in the ordered pair. Next, count the number of spaces to move up until you reach Point B. This will be the second number in your ordered pair.  

 

You should have counted 2 spaces to the right and 8 spaces up. The ordered pair for Point B is (2, 8).

Example Question #3 : How To Find The Points On A Coordinate Plane

Angela plotted points A through E on the coordinate plane shown below.

 

Points_grid

What are the coordinates for Point A?

Possible Answers:

(6, 1)

(1, 6)

(6, 0)

(0, 5)

(0, 6)

Correct answer:

(0, 6)

Explanation:

Begin at point (0, 0) in the bottom left hand corner of the coordinate plane. From there, count the number of spaces you move to the right to line up with Point A. This will be the first number in the ordered pair. Next, count the number of spaces to move up until you reach Point A. This will be the second number in your ordered pair.  

You should have counted 0 spaces to the right and 6 spaces up. The ordered pair for Point B is (0, 6).

 

 

Example Question #4 : How To Find The Points On A Coordinate Plane

Angela plotted points A through E on the coordinate plane shown below.

 

Points_grid

Which point is located at the ordered pair (6, 7)?

Possible Answers:

Point E

Point D

Point A

Point B

Point C

Correct answer:

Point C

Explanation:

Start at point (0, 0) in the bottom, left corner of the the coordinate plane. From there, count right 6 spaces. This is the first number in the given ordered pair. From that point, count up 7 spaces. This is the second number in the given ordered pair.

 

By moving right 6 and up 7, you should have found Point C.

Example Question #5 : How To Find The Points On A Coordinate Plane

Angela plotted points A through E on the coordinate plane shown below.

 

Points_grid

Which point is located at the ordered pair (2, 8)?

 

 
Possible Answers:

Point A

Point C

Point B

Point E

Point D

Correct answer:

Point B

Explanation:

Start at point (0, 0) in the bottom, left corner of the the coordinate plane. From there, count right 2 spaces. This is the first number in the given ordered pair. From that point, count up 8 spaces. This is the second number in the given ordered pair.

By moving right 2 and up 8, you should have found Point B.

Possible Answers:

Kite

Trapezoid

Parallelogram

Square

Pentagon

Correct answer:

Parallelogram

Explanation:

Begin by plotting the points and connecting the vertices.

The quadrilateral that is created has two sets of parallel sides. Out of the possible answer choices, this can describe both squares and parallelograms. Because the figure does not contain right angles and the sides are not all the same length, it must be a parallelogram.

Example Question #2 : How To Find A Parallelogram On A Coordinate Plane

A coordinate plane is shown.

Ralph plotted the following points on the coordinate grid:

Point W (1, 1); Point X (7, 3); Point Y (1, 6); Point Z (7, 8)

A polygon is formed with vertices W, X, Y, and Z. Which type of polygon is formed? 

Possible Answers:

Hexagon

Triangle

Trapezoid

Rhombus

Parallelogram

Correct answer:

Parallelogram

Explanation:

Begin by plotting and connecting the vertices.
