               CH: 8-PLAYING WITH CONSTRUCTIONS


               SUBTOPIC:  AN EXPLORATION IN RECTANGLES

               1. Assertion (A) All squares are rectangles, but not all rectangles are squares.
                   Reason (R) A square has four right angles and all sides equal while a rectangle has only
               opposite sides equal.
               (a) Both A and R are true and R is the correct explanation of A
               (b) Both A and R are true, but R is not the correct explanation of A
               (c) A is true, but R is false
               (d) A is false, but R is true

               2. Assertion (A) The diagonals of a rectangle are equal in length.
                   Reason (R) The diagonals of a rectangle bisect each other at right angles.
               (a) Both A and R are true and R is the correct explanation of A.
               (b) Both A and R are true but R is not the correct explanation of A.
               (c) A is true but R is false.
               (d) A is false but R is true.
               3. A square is a type of rectangle with all sides equal. (True/False)

               4. The diagonal of a rectangle is always shorter than its sides. (True/False)

               5. When constructing a rectangle, we always start with the diagonals. (True/False)

               6. A rectangle can be constructed using only the length of one side. (True/False)


               Answers.
