Answer:
Option D.
Step-by-step explanation:
It is given that triangle ABC reflected in the y axes so that the image of triangle ABC is triangle A'B'C'.
Let A(a,b) and B(c,d). So, after reflection A'(-a,b) and B'(-c,d).
Using distance formula,
So,
We know that reflection is rigid transformation, it means figure and its image must be congruent.
If triangle ABC is read clockwise, then after reflection triangle A'B"C' is read anticlockwise.
Since statements I, II and IV are true, therefore the correct option is D.
I think 10.5 is the right answer.
