Question

If a rotation takes triangle CAT to C'A'T', what is C'T'?

Answer 1

The distance between points C'T' is 4 units

Answer 2

`C'T'=4\ units`

Explanation:

we know that

A rotation does not modify the original length sides of the figure or its internal angles, a rotation only modify the orientation of the figure.

so

The distance CT before the rotation is the same of the distance C'T' after the rotation

CT=C'T'

we have

`CT=4\ units`

therefore

`C'T'=4\ units`
