Q1. A square is a rhombus because the sides of the square and the rhombus are the same length and its is parallel to each other. A rhombus isn't a square because it doesn't have to have 4 right angles.
Q2.All of the above. A quadrilateral is a shape with 4 sides,which is true for both squares and parallelograms. The length and position the sides of the two shapes have makes it parallel to its opposite. A trapezoid has one pair of parallel side
Q3. The figure is a trapezium because it is the only quadrangle that has two sides opposing with the same length and the the other two with different length and vertical pairs of angles are a total of 180 degrees.
Q4.No, all parallelogram is not squares as all sides of a square have the same length. And some parallelograms are rectangles so not all parallelograms are squares.
Q5.BFED is a parallelogram because it has four sides which are parallel to their opposite side and their supplementary angles add up to 1800
Hi zhixiang,
ReplyDeleteGood job!
What is the different between trapezium and trapezoid?
Comment #12
technically, trapezium is a shape with four sides, of which only two are parallel, whereas, a trapezoid is a shape with four sides of which none are parallel. But in American english, they have opposite meaning
