Answer:
Rectangle always have congruent diagonals.
Step-by-step explanation:
Given some figures kite, quadrilateral, rectangle and rhombus. we have to find which of these always have congruent diagonals.
The diagonals of a kite intersect at a right angle and have exactly one pair of opposite angles congruent. But does not have congruent diagonals.
If the quadrilateral is rectangle, square, isosceles trapezoid then only the diagonals are congruent.
Rhombus also does not have congruent diagonals.
The only option whose diagonals are congruent is rectangle.
