B.rotation 180° about the origin
C.translation 10 units right
D.reflection across the y-axis
Answer:
y-axis, x-axis , y-axis and x-axis
Step-by-step explanation:
Given : In triangle ABC
The coordinates are
A = (1,2) , B=(2,4) and C =(3,0)
Rule of reflection:
*Reflecting a point (x, y) across the y-axis will map it to (-x, y).
*Reflecting a point (x, y) across the x-axis will map it to (x, -y).
If you do a reflection on coordinate point A = (1,2) across y-axis we get
then, reflecting a point (-1 , 2) across x -axis we get, (-1, -2)
then, reflecting a point (-1 , -2) across y-axis we get, (1 , -2)
and
reflecting a point (1, -2) across x- axis we get the result same i.e, A =(1,2)
Similarly,
For B = (2,4) across y-axis (-2, 4) across x- axis (-2, -4) across y -axis (2 , -4) across x axis ( 2, 4) = B
for C = (3, 0) across y-axis (-3, 0) across x- axis (-3, 0) across y -axis (3 , 0) across x axis (3, 0) = C
Therefore, the set of reflection would carry triangle ABC onto itself is:
y-axis, x-axis , y-axis and x-axis

it is 0.25 / 1 cause everytime you use 1 with dividing or multiply , it comes out the same like 10 * 1 = 10 hope this helps
