Consider definitions of <u>parallelogram</u>,<u> trapezoid</u>, <u>rectangle</u>, <u>kite</u> and <u>rhombus</u>.
Parallelogram is a quadrilateral with two pairs of parallel opposite sides.
Trapezoid is a quadrilateral with one pair parallel opposite sides, trapezoid is not parallelogram, so option 1 is false.
Rectangle is a parallelogram with all angles right. Rectangle has diagonals that are congruent. Option 2 is true.
Kite is a quadrilateral with two pairs of congruent adjacent sides. Kite is not parallelogram, so option 3 is false.
Rhombus is a parallelogram with all sides congruent. The diagonals of the rhombus are not congruent, but they are perpindicular bisectors of each other. Option 4 is false.
Answer: correct choice is option 2
