Question 1:

‘A square is a rhombus but a rhombus is not a square’.

Rhombus is a quadrilateral whose four sides all have the same length. The angles of a rhombus need not be a perfect angle.

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

D.

A)Squares and parallelograms all have 4 sides.

B)All four sides are of equal length, and all four angles are right angles. An equivalent condition is that opposite sides are parallel. Rhombus is a quadrilateral whose four sides all have the same length.

C)The four-sided figure with one pair of parallel sides is referred to as trapezoid

I) As a/b/c are all correct so is D.

Question 4:

‘All parallelograms are squares?’ Do you agree with this statement?

Justify your answer with example/s.

No, I do not agree with this statement. The angles on a parallelogram does not necessarily need to be 90º. Unlike a square the angle have to be exactly 90º.

ReplyDeleteQ4.

ReplyDeleteWhat you have said is correct and clear.

::: Q2 :::

ReplyDeleteOverall well explained, easy to understand but B) is kinda complicated because i cannot quite get how are angles related to parallel lines.

:::Q4:::

I think you can also add on to say that a square has to have four equal sides. Overall, well pointed out.

I hope my comment makes sense :D
