Is quadrilateral ABCD a rectangle?
(1) All four sides of ABCD are equal.
It can be a rhombus or a rectangle(square) depending on internal angles.
INSUFFICIENT.
(2) All four internal angles of ABCD are equal.
Quadrilateral has sum of four internal angles equal to 360, thus each would be 90.
Either it can be a square or it can be a rectangle. Eventually it will be a rectangle.
SUFFICIENT.

Based on statement 1. it can either be a rhombus or a square, but it sure is not a rectangle, therefore 1. is supposed to be sufficient as well, right? Since we're able to answer the question: is ABCD a rectangle?
