Name the polygon formed when these points (4, 9) , (6, 9) , (4, 2) , and (6, 2) are plotted on a coordinate grid and joined.

a. | a triangle is formed | ||

b. | a rhombus is formed | ||

c. | a square is formed | ||

d. | a rectangle is formed |

Plotting the points on a coordinate plane. The ordered pair (4, 9) is 4 spaces right and 9 spaces up of zero the ordered pair (6, 9) is 6 spaces right and 9 spaces up of zero the ordered pair (4, 2) is 4 spaces right and 2 spaces up of zero and the ordered pair (6, 2) is 6 spaces right and 2 spaces up of zero, which is the starting point.

Joining the ordered pairs.

So, by joining the set of points a rectangle is formed.

Correct answer : (4)

132.

Plot the points (2, 3) , (-2, 3) , (3, -2) , and (-3, -2) and join them to make a polygon. What do you notice?

a. | A quadrilateral is formed. | ||

b. | A circle is formed. | ||

c. | A triangle is formed. | ||

d. | None of the above |

Plotting the points on a coordinate plane. The ordered pair (2, 3) is 2 spaces right and 3 spaces up of zero the ordered pair (-2, 3) is 2 spaces left and 3 spaces up of zero the ordered pair (3, -2) is 3 spaces right and 2 spaces down of zero and the ordered pair (-3, -2) is 3 spaces left and 2 spaces down of zero, which is the starting point.

Joining the ordered pairs.

So, by joining the set of points a quadrilateral is formed.

Identify the vertices of the rectangle in the coordinate plane.

a. | W = (1, 4), X = (1, 2), Y = (3, 2) and Z = (4, 4) | ||

b. | W = (1, 4), X = (1, 2), Y = (5, 2) and Z = (5, 4) | ||

c. | W = (1, 1), X = (2, 2), Y = (5, 2) and Z = (1, 4) | ||

d. | W = (2, 4), X = (1, 2), Y = (5, 3) and Z = (5, 5) |

The point X is 1 space right and 2 spaces up of zero, which is the starting point.

The point Y is 5 spaces right and 2 spaces up of zero, which is the starting point.

The point Z is 5 spaces right and 4 spaces up of zero, which is the starting point.
