Which explains whether kadesha is correct?
kadesha is correct because triangle abc is the pre-image and triangle a'b'c' is the image.
kadesha is correct because each point in triangle abc moves five units up.
kadesha is not correct because the number of units between points a and b is different than those between points a' and b'.
kadesha is not correct because a translation is a horizontal movement

Answer with explanation:

 Coordinates of vertices of ΔABC are =A(1,-1), B(1,-4),C(4,-4)

  Coordinates of vertices of ΔA'B'C' are =A'(1,5), B'(1,1),C(4,1)

Suppose, Preimage =ΔABC

Image =ΔA'B'C'

If you will find distance between two vertices of Both the triangles or length of sides of triangles

Option C is most Appropriate.

Kadesha is not correct because the number of units between points A and B is different than those between points A' and B'.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
