A Rectangle
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.
This is a rectangle.
I assume you mean 4 congruent sides or 2 pairs of congruent sides.. (There are no 4-sided figures with 8 sides.) A square.
a square and a rectangle
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.
