Question

How do I go about solving this?

Answer 1

Explanation:

Hello,

Here i am using vectors

\vec{AB}=\vec{DC}=3\vec{i}+3\vec{j}AB=DC=3i+3j

==> AB//DC and AD//BC (definition of a translation)

The quadrilater ABCD is a parallelogram:

so

1) his diagonals have the same length;

2) his diagonals are cutting in the middle.

(these are proprieties of a parallelogram)
