Question

If the coordinates of a polygon graphed in the first quadrant with one vertex on the origin are (0,0), (a,0), (a,a), (0,a), then what is the most precise name for the polygon? (I have no clue)

A. Rectangle
B. Trapezoid
C. Rhombus
D. Square

Answer 1

If you can, draw a grid on a piece of paper. Remember that coordinates are always listed as (x,y) (i.e. x-coordinate first, y-coordinate second). Then plot your points. Notice that each segment should be of length a.
Here's a hint: what polygon has all four sides congruent?

Answer 2

square has all four sides congruent but I don't understand how to plot a letter

Answer 3

The x-coordinate (first value) tells you how far you should move horizontally on the x-axis (left and right), while the y-coordinate (second value) tells you how far you should move vertically on the y-axis (up or down).

Answer 4

I understand that part but not the letter part

Answer 5

What letter part? The letter "a"?

Answer 6

yes

Answer 7

Make that "a" into some number like 2. Just remember that "a" is the same for all four coordinates.

Answer 8

oooh okay! so its D?

Answer 9

Yeah, it should be a square, as all four sides are of length 'a' and all sides are perpendicu

Answer 10

Perpendicular to each other*
