Answer the following question.
Which of the quadrilaterals have the property stated below?
The two pairs of opposite sides are equal in length:
Rectangle, square, parallelogram, rhombus
1038:
Look at the pictures and answer the questions.
(a) Measure the length of the four sides
W
X
Z
Y
of the shape on the right.
WX:
XY:
3
3
cm
cm
YZ:
3
cm
WZ:
3
cm
Thus, the four sides of this shape are ( all equal / not equal ).
(b) The four angles in this shape ( are / are not ) all right angles.
(c) The opposite side of WX is YZ or ZY. This pair of opposite
sides ( are / are not ) parallel.
The opposite side of XY is WZ or ZW. This pair of
opposite sides ( are / are not ) parallel.
Thus, each pair of opposite sides in this shape ( are / are
not ) parallel.
(d) This shape is a
square .

Look at the pictures and answer the questions.
(a) Measure the length of the four
A
B
D
C
sides of the shape on the right.
AB:
4
cm
BC:
2
cm
CD:
4
cm
AD:
2
cm
The opposite side of AB is DC or CD.
The opposite side of BC is AD or DA.
Thus, each pair of opposite sides in this shape ( are / are not )
equal in length.
(b) AB and CD ( are / are not ) parallel.
BC and AD ( are / are not ) parallel.
Thus, each pair of opposite sides in this shape (are / are not)
parallel.
(c) The four angles in this shape ( are / are not ) all right angles.
(d) This shape is a
rectangle
.
1040:
Look at the quadrilaterals below and answer the questions.
Blue
Red
Red
Blue
(a) Colour the squares in blue. Then, colour the rectangles
among the quadrilaterals remained in red.
(b) Write the name of those quadrilaterals not coloured?
They are
parallelograms
.
(c) Each pair of opposite sides of parallelograms ( are / are not )
equal in length.
Each pair of opposite sides of parallelograms ( are / are not )
parallel.
Each pair of opposite angles of parallelograms ( are / are not )
equal in size.

Answer the following questions based on table above.
(b) Which kinds of quadrilaterals must have four sides equal in
length?
Square and rhombus
(c) Which kinds of quadrilaterals must have four right angles?
Square and rectangle
(d) Does a square contain an extra property than a rhombus? If
yes, what is it? (Put a ‘’ in the correct box.)
No.
Yes, the extra property is ‘

A shape card is lost
Lily lost a quadrilateral shape card.
One of the cards
belongs to Lily.
Answer the following questions based on what Lily said.
(a)
The four sides of my shape
card are not all equal in length.
Which shape cards meet this property?
Rectangle, parallelogram, trapezium
(b)
Besides, the four angles in my
shape card are not right angles.
Which shape cards still meet this property?
Parallelogram, trapezium
(c)
In addition, my shape card can be
divided into 2 equal triangles.
Which shape card can meet this property?
Parallelogram
(d) So the shape card that Lily lost is a
parallelogram
