Graph the image of the given triangle after a rotation of 180° about the origin. Select the Polygon tool. Click the points of the triangle vertices to create the triangle by connecting the sides.

(Pictorial representation is provided in the attached image.)

The given triangle's coordinates are (-1, 1) (-2, 6) (-5, 4)

When we rotate any polygon by 180° in a Cartesian plane, we simply change the positive coordinates to negative and vice versa.

Thus, the coordinates of the now rotated triangle are,

(1, -1) (2, -6) (5, -4)

Hope this helps :)

mordancy.

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
