Question

Please help thank you.

Answer 1

Question 1:

The answer is the second choice.

Parallelograms that are not rectangles do not have congruent diagonals; however, all rectangles do have congruent diagonals.

A rhombus has perpendicular diagonals but is not a rectangle, so the first choice is wrong

A rhombus has all congruent sides but is not a rectangle, so the third choice is wrong.

The last choice only applies to certain quadrilaterals, none of which are rectangles.

Question 2:

The first choice is the answer.

A rectangle has congruent diagonals, but is not a square. We can eliminate the second choice.

A rhombus has all congruent sides, but it is not a square.

The last choice only applies to certain quadrilaterals, none of which are squares.

Have an awesome day! :)
