One quadrilateral is done for you. Side lengths square 9cm 9cm 9cm 9cm rectangle rhombus kite 3cm 9cm 10cm Q2. Liam has two rectangular tiles like this. He makes this L shape. What is the perimeter of Liam s L shape? cm Page 1
Q3. Here is a square grid. International School of Madrid Two sides of a kite are drawn on the grid. Complete the kite by drawing the two missing sides. Use a ruler. Q4. This is a centimetre grid. Draw 3 more lines to make a parallelogram with an area of 10cm 2 Use a ruler. Page 2
Q5. On the grid below, use a ruler to draw a pentagon that has three right angles. Q6. Here is a grid of dots. Point A and point B are joined by a straight line. Draw a line to join point A to another dot on the grid so that the two lines make a right angle. Use a ruler. Page 3
Q7. Here is a shape on a square grid. For each sentence, put a tick ( ) if it is true. Put a cross ( ) if it is not true. Angle C is an obtuse angle. Angle D is an acute angle. Line AD is parallel to line BC. Line AB is perpendicular to line AD. Page 4
Q8. Jamie draws a triangle. He says, Two of the three angles in my triangle are obtuse. Explain why Jamie cannot be correct. Q9. Here are four statements. For each statement put a tick ( ) if it is possible. Put a cross ( ) if it is impossible. A triangle can have 2 acute angles. A triangle can have 2 obtuse angles. A triangle can have 2 parallel sides. A triangle can have 2 perpendicular sides. Page 5
Q10. An isosceles triangle has a perimeter of 12cm. One of its sides is 5cm. What could the length of each of the other two sides be? Two different answers are possible. Give both answers. cm and cm cm and cm Q11. Triangle ABC is isosceles and has a perimeter of 20 centimetres. Sides AB and AC are each twice as long as BC. Calculate the length of the side BC. Do not use a ruler. Page 6
Q12. Here is a regular octagon with two vertices joined to make the line AB. Join two other vertices to draw one line that is parallel to the line AB. Here is the octagon again. Join two vertices to draw one line that is perpendicular to the line AB. Page 7
Q13. The diagram shows four lines drawn on a square grid. The lines are AB, BC, CD and DA. Which two of the lines are parallel? Circle them in the list below. AB BC CD DA Which two of the lines are perpendicular? Circle them in the list below. AB BC CD DA Page 8
