Explain why a square can be classified as a rectangle, but a rectangle cannot be classified as a square.
A rectangle is a quadrilateral with four right angles. Since a square has those attributes, it can be classified as a rectangle.
A square has four equal sides and a rectangle does not, therefore and rectangle cannot be classified as a square.

If the sum of the angles in a quadrilateral is always 360 degrees, find the value of w 
We are giving the value of one angle which is 146 degrees.
The angles with squares indicate 90 degree angles.
If we have 90 + 90 + 146, and we know the total is 360, how much more do we need to get to 360?
360-90-90-146=34
Angle w = 34 degrees
