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? Select two options.

Answer 1

Answer: C & D

Step-by-step explanation: Ro 270, Ro -90

Answer 2

As you are only given one point the choices are quite numerous:

A. Quarter turn rotation clockwise about the origin

B. Reflection in the line y = x

C. Translation using the vector (5 -5). [5 right and 5 down]

D. Half turn rotation about point (2.5, 2.5)

E. Reduction with scale factor 1/2 with centre at (10, -5)

The last two are not likely but still only require a single transformation
