T4S1b： 362： Answer the following question. Which of the quadrilaterals have the property stated below? All the four angles are right angles. 363： Answer the following question. Which of the quadrilaterals have the property stated below? The two pairs of opposite sides are equal in length: 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: cm cm YZ: cm WZ: 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 . This pair of opposite sides ( are / are not ) parallel. The opposite side of XY is . 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 . 1039: 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: cm BC: cm CD: cm AD: cm The opposite side of AB is . The opposite side of BC is . 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 . 1040: Look at the quadrilaterals below and answer the questions. (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 . (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. 1041: (a) Give a ‘’ to the property of the quadrilateral in the table below. Only one pair of opposite angles are equal in size. Only one pair of opposite sides are equal. Adjacent sides are equal in length. Each pair of opposite sides are parallel. Each pair of opposite sides are equal in length. Each pair of opposite angles are equal in size. The four angles are right angles. The four sides are equal in length. Square Rectangle Parallelogram Trapezium Rhombus Answer the following questions based on table above. (b) Which kinds of quadrilaterals must have four sides equal in length? (c) Which kinds of quadrilaterals must have four right angles? (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 ‘ ’. (e) Which kind of quadrilateral must have only one pair of opposite parallel lines? (f) Which kinds of quadrilaterals have all the properties of a parallelogram? 1166： 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? (b) Besides, the four angles in my shape card are not right angles. Which shape cards still meet this property? (c) In addition, my shape card can be divided into 2 equal triangles. Which shape card can meet this property? (d) So the shape card that Lily lost is a . 1167： Colour the quadrilaterals with four sides equal in length.
