Troy drew a triangle with coordinates ( 5 , 6 ) , ( 5 , 4 ) , and ( 8 , 4 ) . he rotated the triangle 180° about the origin. what are the coordinates of the image? select all that apply.
a. (−5, 6)
b. (−5, −4)
c. (−5, −6)
d. (−8, −4)
i hate doing this but i really dont know the answer and im already failing : (

The answers are B, C, and D.

Step-by-step explanation:

When you rotate an image 180° about the origin, you are flipping it twice. An easy rule is that an (x, y) pair becomes (-x, -y). Now just reverse the sign of the coordinates. Our rotated shape has the coordinates (-5, -6), (-5, -4), and (-8, -4).

 C. (−5, −6)          D. (−8, −4)

Step-by-step explanation:

We know that the rule for rotation a shape by (counterclockwise or clockwise) is given by :-

 [Polarity of coordinates gets changed]

Given : Troy drew a triangle with coordinates ( 5 , 6 ) , ( 5 , 4 ) , and ( 8 , 4 ) . He rotated the triangle 180° about the origin.

Then, the coordinates of the image will be :-

From the options, the coordinates of the image = (-5,-6) and (-8, -4)

Hence, option C and D are correct.
