Q 1,2 and 4 done by Daniel and Alpha

Q1)A square is a rhombus because it has sides of equal length and they are all parallel to the opposite side.A rhombus is not a square because although it has sides of equal length and sides parallel to the opposite,there are no right angles.(90 degrees)

Q2)All of the above.A quadrilateral is a shape with 4 sides,which is true for both squares and parallelograms.Squares and parallelogram have sides that are parallel to the opposite as any quadrilateral without both pairs of sides being parallel is a trapezium.The only quadrilateral with just one pair of parallel lines is the trapezium.Any quadrilateral without any parallel lines is not a quadrilateral.

Q5)Parallelograms have the top and bottom pair shorter than the left and right pair.Sides of opposite sides also are parallel in a parallelogram.If the shape is slanted and meets the following requirements,the shape is a parallelogram.

  1. Good collaborative effort from both of you. If A is a member of B does not necessarily mean that B is a member if A. Check out the term 'subset' and use it in your argument.
