Question

△QRS is mapped to △Q'R'S' using the rules (x, y)→(−x, y) followed by (x, y)→(x−1, y+2).
Which statement describes the relationship between △QRS and △Q'R'S'?

Answer 1

A. △QRS is congruent to △Q'R'S' because the rules represent a translation followed by a rotation, which is a sequence of rigid motions.

B. △QRS is congruent to △Q'R'S' because the rules represent a reflection followed by a rotation, which is a sequence of rigid motions.

C. △QRS is not congruent to △Q'R'S' because the rules do not represent a sequence of rigid motions.

D. △QRS is congruent to △Q'R'S' because the rules represent a reflection followed by a translation, which is a sequence of rigid motions.

Answer 5

Sorry for being late for you!

Are you familiar with that?
These are kinds of reflections:
Reflection across x-axis: (x, y) > (x, -y)
Reflection across y-axis: (x,y) > (-x, y)
Reflection over origin: (x,y) > (-x,-y)
Reflection over line y=-x: (x,y) > (-y,-x)

Answer 6

yes but i don't understand what the question is asking

Answer 7

"△QRS is mapped to △Q'R'S' "
so there is\are transformation will happen to the triangle QRS!

using the rules:
1.(x, y)→(−x, y)
followed by
2.(x, y)→(x−1, y+2)

What is the first transformation and what is the second transformation?

Is it clear so for?


It is recommended to graph the triangle in general case in any quadrant!

@itsbribro
Still need help?

Answer 9

ok

Answer 10

So what do you think of the first transformation?

Answer 11

why did you closed it?
