HELP ME *** if you give the wrong answer you will be reported Given triangle ABC with A(2, 3), B(0, 6), and C(2,6). Determine if the image A"B"C" is congruent to it's pre-image ABC after the following transformation; dilation of scale factor 1, rotation about the origin of 180 degrees, and a reflection over the line y = -1. Explain your answer.

Step-by-step explanation:

The image and a pre-image after dilation with coefficient 1 are congruent.

The other endpoint is (-4, -5)

Step-by-step explanation:

We know the formula for the coordinates of the point dividing the line segment in the ratio of a : b is

x = x' +

y = y' +

Now we plug in the values of endpoints (8, -1) and (x, y) with a point (5, -2) dividing the segment in 1 : 3 ratio.

5 = 8 +

5 - 8 =

(x - 8) = -3×4 = -12

x = -12 + 8 = -4

Similarly, -2 = -1 +

-2 + 1 =

y + 1 = -1(4)

y + 1 = -4

y = -1 - 4 = -5

Therefore, another endpoint of the segment is (-4, -5).
