Square
It is a rectangle.
Two different quadrilaterals have two pairs of parallel sides and have all their angles congruent. They are the square and the rectangle.
It has 2 pairs of parallel sides and the opposite angles are congruent.
Rectangle
The definition of a rectangle: A figure that has 4 right angles, has congruent diagonals that bisect, has 2 pairs of parallel sides, and has 2 pairs of opposite congruent angles. A square has all of the above, and thus, is a rectangle by definition.
A rectangle has three rules: -2 pairs of parallel sides -four 90 degree angles -2 pairs of congruent sides A parallelogram has three rules: -2 pairs of parallel sides - 2 pairs of congruent angles -2 pairs of congruent sides The only difference is that a rectangle has 90 degree angles, which a parallelogram doesn't have. That's why a parallelogram can't be a rectangle. A rectangle follows all the rules of being a parallelogram, so it can be a parallelogram.
A square. A rectangle.
Iy is either a 'Parallelogram' or a 'Rhombus'.
Parallelogram -- 2 pairs of parallel sides Trapezoid -- exactly 1 pair of parallel sides Rhombus -- 4 congruent sides Rectangle -- 4 angles congruent Square -- four angles and sides congruent
* both pairs of opposite sides are parallel * both pairs of opposite sides are congruent * all angles are 90 degrees * both pairs of opposite angles are congruent * the diagonals bisect each other.
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)
Parallelogram -- 2 pairs of parallel sides Trapezoid -- exactly 1 pair of parallel sides Rhombus -- 4 congruent sides Rectangle -- 4 angles congruent Square -- four angles and sides congruent
