### What has 4 right angles and and 2 congruent sides?

There is no shape with exactly 4 right angles and 2 congruent
sides.
A rectangle has 4 right angles and 2 pairs of congruent
sides - 4 sides in all. But if the numbers in the question are not
limiting, then there are many more shapes. An irregular hexagon
with the following shape, will meet the requirements if its height
is the same as its base.
___
|....\
|......\___
!_______|
There are lots more shapes with more sides.

### How do you describe the angles and sides of each quadrilateral?

quadrilateral--a four-sided figure, any length sides, any
angles
trapezoid--one pair of parallel sides, any length sides, any
angles
parallelogram--two pairs of parallel sides, opposite sides
congruent, opposite angles congruent
rectangle--two pairs of parallel sides, opposite sides
congruent, all angles are right angles (90 degrees)
rhombus--two pairs of parallel sides, all sides congruent,
opposite angles congruent
square--two pairs of parallel sides, all sides congruetn, all
angles are right angles (90 degrees)

### If two triangles have three pairs of congruent angles the the triangle is congruent?

Yes they are. Or they could have three pairs of congruent sides,
or they could have one pair of congruent angles and two pairs of
sides. As far as a triangle goes, if you have at least three pairs
of congruent sides or angles they are congruent.
This answer is wrong. The triangles are only similar.
For congruent trisngles we have the following theorems = Side -
side - side,
Side - Angle - side , Angle - angle - side, Right triangle -
hypotenuse - side.

### How is a parallelogram different a rectangle?

These shapes are different in some ways:
A parallelogram contains two pairs of congruent angles such
that they are not adjacent to each other. A rectangle contains all
four right angles.
The diagonals of both shapes are formed differently from
another.
A parallelogram has a pair of congruent parallel slanted sides
while a rectangle doesn't.
