Question

Missy’s rotation maps point k (17,12) to k(12,17).which describes the rotation?

Answer 1

Reflection across the line y= x

Explanation:

We are given that Missy's rotation maps point K(17,12) to K(12,17).

We have to find the type of rotation.

We can see that

Initially, we have x=17 and y=12

After rotation ,we have

x=12 and y=17

It means x changes into y and y changes into x.

Reflection across the line y=x:

When a figure is rotated across the line y=x then, the translation rule is given by

`(x,y)\rightarrow (y,x)`

Therefore, this is a reflection across line y=x
