Answer 1

1. D ... B and C are both possible, as well as squares and some asymmetrical quadrangles...parallelograms would only work if they were rectangles (or squares).

2. A ... if one of the angles of a parallelogram is 90 degrees, they all are, hence a rectangle (C is possible, but not enough information is given...besides, all squares are rectangles)

3. B ... We don't know the angles, but with 4 equal sides, it can't be other than a rhombus...if it is formed at 90 degrees, then it could be a square, so A is possible but not guaranteed (even so, all squares are rhombi, so B is still the correct answer)

4. C ... quadrilaterals have a total interior angle sum of 360 degrees...all 4 are equal, so they are all 90 degrees. A quadrilateral with 4 right angles is a rectangle (it's also one of many parallelograms and could be a square as well, but C is correct)

5. B ... squares, rectangles and rhombi all do this, but squares, rectangles and rhombi aren't the only shapes that do...but any parallelogram will do this regardless of dimensions.

6. C ... we don't know the other two angles, , so A, B, and D are possible but not guaranteed...but C will be correct regardless.

7. D ... you could come up with anything from a rectangle to a kite shape.
