rectangle
A Rectangle
A trapezoid.
isosceles
you can assume that the angles are congruent, but not the sides.
A square because that is the only possible figure that can have two congruent sides and four right angles.
All sides congruent = square Two pairs of mutually congruent sides = rectangle
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)
a rectangle......
A rectangle has two pairs of congruent sides, but any pair of adjacent sides is non-congruent.
A parallelogram cannot have only two congruent sides, nor only two congruent angles.
A quadrilateral with 4 right angles cannot have just two congruent sides so, unless this is a trick question (2 congruent sides does not excluded the possibility of more than 2 congruent sides), the answer is there is no such plane figure.
If they have identical sides and angles then they are congruent
How about an isosceles triangle of which 2 of its 3 sides are congruent and 2 of its 3 angles are congruent
How about an isosceles triangle of which 2 of its 3 sides are congruent and 2 of its 3 angles are congruent
That is how it is defined: parallelograms have two sides that have congruent adjacent angles, so that the remaining two sides must be parallel and equal in length. Parallelograms include rectangles (all right angles), squares (all right angles), rhomboids, and rhombi (the latter two have congruent but non-right angles, and a rhombus has 4 equal sides).
