Step-by-step explanation:

There are no marks to conclude that the sides of the triangle are congruent, it doesn't mean they're not, it just means there is a chance that the side-side-side is out. I am not sure if the AB=C is referring to the angles A, B and C, or if it referring to line segment AB.
Answer:
- Yes, vector u and vector v are equivalent vectors.
Step-by-step explanation:
The value of a vector is the difference between its terminal point and its initial point:
u = P2 -P1 = (6-8, 5-3) = (-2, 2)
v = P4 -P3 = (9-11, 10-8) = (-2, 2)
Vectors u and v are both (-2, 2), so are equivalent vectors.
