Question

One vertex of a triangle is located at (0, 5) on a coordinate grid. After a transformation, the vertex is located at (5, 0).

Which transformations could have taken place? Check all that apply

Answer 1

Which transformations could have taken place? Check all that apply
R0, 270°

R0, -90

Answer 2

Let


`A(5,0)`
be the vertex of the triangle.

Now after the transformation the image has coordinates


`A'(0,5)`

We can observe that, if you
`<b>swap</b>`the coordinates of A, you get the coordinates of A'.

A transformation in which the coordinates of the
`<b>pre-image</b>` has been swapped to obtain the

`<b>image</b>` is a reflection in the line

`y = x`

Another possible transformation is a rotation through an angle of

`90 \degree`
clockwise, which is the same as

`270 \degree`
counterclockwise.

See diagram.
