Question

Which of the following is a true statement?

A. All squares are rectangles
B. All rectangles are squares
C. All rhombuses are squares

Answer 1

Answer: Option 'A' is correct and true.

Explanation:

Square is the quadrilateral whose all sides are equal and all angles are right angles and

Rectangle is the quadrilateral whose opposite sides are equal and all angles are right angles.

so, All squares are rectangle as it satisfied the angle property of rectangle and opposite sides of square is also equal.

But all rectangles can't be a square as in rectangle all sides are not equal.

And all rhombus can't be squares as in square all angles are of right angles but rhombus does not possess such property at all.

Hence, Option 'A' is correct and true.

Answer 2

A rectangle is a parallelogram with interior right angles.
That description applies very satisfactorily to squares.
A square is a special kind of rectangle, so all squares are rectangles.

(All squares are rhombuses, parallelograms, and quadrilaterals too.)
