1. An art student uses strips of paper to form a quadrilateral with congruent diagonals. This quadrilateral must be a ____.
2. On a blueprint for a house, if the master bedroom is a parallelogram with at least one right angle, then the master bedroom will be the shape of a _____.
3. If a framer makes a quadrilateral frame out of four congruent boards, no matter how it is put together this frame will always be a _____.
4. A quadrilateral foundation with four congruent angles must be the shape of a ____.
The options are:
an isosceles trapezoid
a square
a rhombus
a parallelogram
a rectangle
no guaranteed classification
a trapezoid
If you can get the all correct first I will give you 10 points! Thanks!

1 no guaranteed classification. Try this on your own,if diagonals intersect at their midpoints, they can be any shape, as long the figure has 4 sides.
2 rectangle. This one is pretty obvious.
3 rhombus, not square because square is a subset of rhombus and the question does not specifiy the figure to have 90 degrees angles.
4 rectangle, not square because rectangle is a superset of square and the question asks for "must be." A quadrilateral foundation with four congruent angles "could be", but not "must be" a square.

Look at your geometry book. Review the different shapes that you listed, and find out what their properties are. (For example, I bet one of those shapes has congruent diagonals!) You've been asking a lot of questions that really... you need to learn how to answer yourself. When the test comes you can't pull up Yahoo Answers!

Sheitzen is correct.
Plus, there are several answers in this group that are just flatass *wrong*
How are you going to seperate them out?
