Question

in a parallelogram the diagonals are not equal. Then how square, rectangle and rhombus are parallelograms?

Answer 1

Step-by-step explanation:

in parallelogram the diagonals are bisect of each other.

in square and rhombus diagonals are perpendicular bisector of each other

in rectangle diagonals are bisect each other

Answer 2

Answer:

Square, Rectangle and rhombus are a parallelogram

Step-by-step explanation:

In a parallelogram, Diagonals bisect each other and in rhombus, square or rectangle diagonals are the perpendicular bisector of each other and they cut all each other at 90°

As we know that square, rhombus or rectangle all have 90° angle with their side, But in a parallelogram, Side do not make 90° angle

As we know that in parallelogram opposite sides are parallel and equal, Therefore its diagonals are not equal
