Ivahew [28]

Answer:

Correct option is A

Step-by-step explanation:

Given some statements we have to choose the correct statement.

A. Square BCDF is a rectangle.

As we know, all the properties of rectangle satisfied by square. Therefore, we say that all squares are rectangles. hence, Square BCDF is a rectangle is true statement.

B. Rectangle GJKM is a square.

As explained in above, all the properties of rectangle satisfied by square but its converse is not true i.e all rectangles are not square. Hence, Rectangle GJKM is a square is not always true.

C. Quadrilateral STPR is a trapezoid.

All the properties of trapezoid are not satisfied by all quadrilateral hence, not always true.

D. Parallelogram ABCD is a rhombus

All the properties of rhombus are not satisfied by parallelogram like all sides of rhombus are congruent but parallelogram has only opposite sides congruent. hence, not always true.
