Ans: Answer D is correct. Quadrilaterals means four sided figures. A square or a parallelogram has four sides. Quad means quadruple which is four. Opposites sides of a square or a parallelogram are parallel to each other. A trapezium has two parallel sides.

Question 4: All parallelograms are squares?’ Do you agree with this statement? Justify your answer with example/s.

Ans: No, not all parallelograms are squares, although a parallelogram can be a square. Parallelograms sides are not equal but parallel to each other while for a square, all sides are equal.

Question 5: Reason why BFDE is a parallelogram.

Ans: It is because the opposite sides are parallel to each other and they have an equal length.

Great work Benz : just my comment

ReplyDeleteQuestion 4

Good to include examples of parallelogram that are not squares. Such as rectangles

Hi Benz,

ReplyDeleteI thought that you did a good job, especially on the explanation! One will immediately understand a parallelogram and quadrilateral just by looking at your work! But I also agree with the comment above, you should include more examples, in case people needs some reference to how to apply it in work, not just the definition. Keep up the good work!

Hello,

ReplyDeleteJust to comment: For Question 2, the question stated a trapezoid and not a trapezium. According to the dictionary and the internet, there is a difference between trapezoid and trapezium. In British maths, a trapezoid is a quadrilateral with no sides parallel. So is it true?

Other than that, the rest of the answers are well constructed and easy to understand. Well done(:

Hello Benz,

ReplyDeleteI thought you did really well in explaining and constructing your answer, so keep it up XD But i found a problem; Question 2. The question stated a trapezoid and not a trapezium. According to my own knowledge, there is a difference between trapezoid and trapezium.

So other then Question 2, the rest is well structured :)
