Questions 1,2,5 elearning Goh Jia SHeng

This is the example for C

This is the example for B,
Based on the above conversation discuss, with examples and justification whether the following statement is justified.
‘A square is a rhombus but a rhombus is not a square’.
This is because the rhombus have equal length but different angles while the square have four sides which have equal length and all are right angles.

Question 2:

Which of the given statements is correct? Justify your answer/s with examples.

A ) A square and a parallelogram are quadrilaterals.

B ) Opposite sides of a square and a parallelogram are parallel.

C ) A trapezoid has one pair of parallel sides.

D ) All the above

The answers is all of the above.It is because quadrilateral just means "four sides" and the square and parallelogram have four sides,thus A is correct.B is correct as as both the square and the parallelogram have two parallel lines.(ABOVE) C is actually a trapezium which have two lines that will be parallel. Thus the answer will be all the above.

Question 5:

ABCD is a parallelogram. If E is midpoint of AD and F is midpoint of BC show, with reasons, that BFDE must be a parallelogram.

BFDE is a parallelogram as BA and CD is parallel while AD and BC is parallel thus when any line is cut in the middle and to end at one corner,it will be parallel to the other side of the BFDE parallelogram.

Sorry for the late submission.


  1. Hi Jia Sheng,

    I'll like to comment on Q5. You said that 'when any line is cut in the middle and to end at one corner, it will be parallel'. That may not be necessarily true. Is the line even straight? And what do you mean by corner? Other than that, the rest of the answers are correct. Good work though.


  2. Hello Jia Sheng,

    Great Job for the overall! However, I do not understand when you said "and to end at one corner" in Q5. Perhaps you can explain more clearly.

    Great Job though! Keep it up!


  3. Hi Jia Sheng!

    Great job! Your questions were finely detailed and understandable. Although I would suggest adding is paragraphs to organise you answers. As the rest says, Q5 has an error which was not clear enough. Does "To the end at one corner" mean to both sides of the parallelogram?
