What are needed in order to considered a kite? 

adjacent sides are the same length

300

What is all the possible names of this shape? 

Rhombus, Kite, Parallelogram, Trapezoid, Quadrilateral  

400

What is needed to be considered a rectangle? 

2 sets of parallel lines and 4 right angles

Billy says this shape is a trapezoid. Sally says the shape is parallelogram. Who is correct and why?  

They are both correct. A trapezoid needs at least 1 pair of parallel lines and this figure does. It is also a parallelogram because you need 2 sets of parallel lines which this shape has. They are both correct because they are naming different subcategories.
