Activity 3 eLearning - Benjamin Fheng

Question 1 

"A square is a rhombus but a rhombus is not a square"
I agree with the statement as a square has four equal sides just like a rhombus. But however a rhombus cannot be a square as a rhombus does not have angles that are all 90 degrees.

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


I choose D as a square and a parallelogram are quadrilaterals which means the shape has four sides. The opposite sides of a square and parallelogram are parallel to one another and a trapezoid is a four sided figure with a pair of parallel sides.


Question 4

'All parallelograms are squares?' Do you agree with this statement?
Justify your answer with example/s.

I disagree with the statement as not ALL parallelograms are squares. Parallelograms are squares only if all four sides are of the same length and all interior angles are 90o.
