Answer:
see explanation
Step-by-step explanation:
Under a rotation about the origin of 180°
a point (x, y ) → (- x, - y ), thus
A(1, 1 ) → A'(- 1, - 1 )
B(1, 4 ) → B'(- 1, - 4 )
C(3, 1 ) → C'(- 3, - 1 )
Answer:
The image of vertex B or the image of Vertex C are:
B '(2, -1)
C '(3, 2)
Step-by-step explanation:
For this case we have the following vertices:
A (-1,1) --------> A '(3, -1)
B (-2.1)
C (-1,4)
We note that the translation rule is:
(x, y) -----------> (x + 4, y-2)
Applying the translacion rule we have:
B (-2, 1) -----------> (-2 + 4, 1-2) ------> B '(2, -1)
C (-1, 4) -----------> (-1 + 4, 4-2) ------> C '(3, 2)
