Example 10

Construct a trapezium PQRS such that PQ = 9 cm, ^QPS = 60°, /LPQR = 70° and the
height of the trapezium is 5 cm.

Solution

Draw a line PO = 9 cm. H-
^ P 9 cm

Using a protractor, draw /.P = 60° and ZQ = 70°.

9 cm

Using a ruler and set square, draw a line parallel to line PQ. Label the
5 intersection points R and 5.

square

Draw the line RS to complete
^ the trapezium. Add in 2 arrow
heads to show that line
PQ is parallel to line RS.
