Answer:
The coordinates of B' and C' are and
, respectively.
Step-by-step explanation:
From the Linear Algebra, we define the translation of a given point as:
(1)
Where:
- Original point, dimensionless.
- Translation vector, dimensionless.
- Translated point, dimensionless.
If we know that and
, then the translation vector is:
(2)
If we know that ,
and
, then the translated points are, respectively:
(3)
The coordinates of B' and C' are and
, respectively.
