Name the type of quadrilateral formed, if any, by the following points, and give reasons for your answer:
 
\(A(2, 6), \ B(7, 6), \ C(8, 8), \ D(3, 8)\) 
 
Answer:
 
Length of \(AB\) \(=\)
 
Length of \(BC\) \(=\) i
 
Length of \(CD\) \(=\)
 
Length of \(DA\) \(=\) i
 
Length of \(AC\) \(=\) i
 
Length of \(BD\) \(=\) i
 
It is observed that, of the given quadrilateral are of length.
 
Also, the diagonals are of lengths.
 
Therefore, the given vertices forms a .
