Question

What transformations were applied to ABC to obtain A’B’C’

Answer 1

Answer:    Im pretty sure it is D

Step-by-step explanation:  I don't really know how to explain it.

I hope it helps tho ;)

Tell me if im wrong.

Answer 2

Answer:  The correct option is

(D) rotation of 270 degrees counterclockwise and shifting 3 units up.

Step-by-step explanation:  We are given to select the correct transformations that were applied to triangle ABC to obtain triangle A'B'C'.

From the graph, we note that

the co-ordinates of the vertices of triangle ABC are A(3, 4). B(5, 6) and C(8, 1).

And, the co-ordinates of the vertices of triangle A'B'C' are A'(4, 0), B'(6, -2) and C'(1, -5).

We see that

if a point (x, y) is rotated 270 degrees counterclockwise and then shifted 3 units up, then its co-ordinates becomes

(x, y)   ⇒   (y, -x+3).

With this transformation rule,

A(3, 4)  ⇒  (4, -3+3) = (4, 0),

B(5, 6)  ⇒  (6, -5+3) = (6, -2)

and

C(8, 1)  ⇒  (1, -8+3) = (1, -5).

Since the resulting co-ordinates are the vertices of triangle A'B'C', so the required transformations rare

rotation of 270 degrees counterclockwise and shifting 3 units up.

Option (D) is CORRECT.
