Question

Triangle ABC is rotated to create the image A'B'C'.

Answer 1

Answer:

The transformation used here is,

(x, y) → (-x , -y)

Step-by-step explanation:

Triangle ABC is rotated to create the image of triangle A'B'C'

Co-ordinates of A, B, C are,

A = (-1 , -1) ; B = (1 , -1) ; C = (0, -4)

Co-ordinates of A' ,B' , C' are,

A'= (1 , 1) ; B' = (-1 , 1) ; C' = (0, 4)

Hence, the transformation used here is,

(x, y) → (-x , -y)

Answer 2

Answer:

(x, y) → (–x, –y)

Step-by-step explanation:

Coordinates of triangle ABC:

A (-1, -1)

B (1, -1)

C (0, -4)

If we apply the transformation (x, y) → (–x, –y) we will get:

A (-1, -1) → (1, 1)   which correspond to point A'

B (1, -1) → (-1, 1)   which correspond to point B'

C (0, -4) → (0, 4)   which correspond to point C'
