    • 90 degrees

  5. An angle measures 65 degrees on a protractor. Which type of angle is it?

    • Reflex, more than 180 degrees
    • Right, exactly 90 degrees
    • Acute, less than 90 degrees
    • Obtuse, between 90 and 180 degrees

    • An angle of 45 degrees
    • An angle of 90 degrees

  7. When measuring an angle with a protractor, what is the first step?

    • Start the ruler at the far end of one arm
    • Draw a circle around the whole angle
    • Place the centre mark on the vertex of the angle
    • Measure the longest arm of the angle only

  8. A scale drawing uses 1 cm to represent 2 m. A wall is 5 cm long on the drawing. How long is the real wall?

    • 7 m
    • 10 m
    • 5 m
    • 2.5 m

    • 4.3 m
    • 7 m
    • 12 m
    • 3.4 m

  13. When drawing a 75 degree angle, which steps are correct?

    • Draw one arm, put the protractor centre on the vertex, mark 75 degrees, then draw the second arm
    • Draw one arm, put the protractor centre on the vertex, mark 105 degrees, then draw the second arm
    • Draw one arm, place a ruler on the vertex, measure 75 cm along the arm, then draw the second arm
    • Draw one arm, put the protractor centre on the far end, mark 75 degrees, then draw the second arm

  14. Which unit is best for measuring the length of a pencil on a design drawing?

    • Litres (l)
    • Tonnes (t)
    • Kilometres (km)
    • Millimetres (mm)

  15. Why should you read a ruler by looking straight down at the mark?

    • To change the scale of the ruler
    • To make the line look longer
    • To stop the paper from moving
    • To avoid parallax error
