Which of the following statements are true?
statement 1: a parallelogram is always a rectangle.
statement 2: a square is always a rhombus.
statement 3: a rectangle is always a square.
plz need this

 statement 2: a square is always a rhombus.

Step-by-step explanation:

A parallelogram does not have all the interior angle as right angle.

Therefore, it does not satisfy property of rectangle.

A square has all sides equal and its diagonals are perpendicular bisector.

Thus,  square satisfies all the properties of rhombus .

A rectangle does not have all the sides are equal.

Therefore, it cannot b e a square.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
