Question 1, 2, and 4 by Goh Jin Hao

Question 1
The statement is not justified as although all the sides of both the rhombus and the square are equal, the corners of a square must be exactly 90 degrees so a rhombus cannot be a square which makes the statement unjustified.

Question 2
D ) All of the above
Both squares and parallelograms are quadrilaterals as they both have four sides.
Both the squares' and the parallelograms' opposite sides are parallel as the other two sides are of equal length.
A trapezoid has a pair of parallel sides as it is made out of a rectangle and a triangle and a rectangle has a pair of parallel sides.

Question 4
I do not agree with the statement. A parallelogram cannot be a square as all corners of the square must be 90 degrees and all of the sides must be equal.
