CONSTRUCTION PRACTICE:

1. Construct a triangle PQR, such that PQ = 4.5cm, PR = 3.5cm and RQ = 7cm

2. Construct a trapezium ABCD, such that AB is parallel to DC; AB = 7cm, AD = 3cm and DC = 2cm

3. Draw a straight line, label a point B on it (about two thirds of the way along). Construct a 90 degree angle at the point B.

4. Construct a triangle PQR, such that angle RPQ is a 90 degree angle, PQ = 5cm and RQ is 5.5cm.

5. Construct a rhombus ABCD with diagonals 12cm and 6cm. Measure how long the sides are. Check the accuracy of your diagram by calculating the length of one side.

6. Draw a line PQ. Construct a perpendicular bisector of PQ.

7. Construct a right angled triangle ABC (any reasonable size). Bisect the hypotenuse and label the midpoint of this side M. Draw a circle with diameter equal to the length of the hypotenuse and centre M.

8. Draw an acute angle just less than 90 degrees. Bisect this angle.

9. Without a protractor construct a 45 degree angle.

10. Plot two points about 3 cm apart and label them A and B. The point S is equidistant from the points A and B and exactly 2cm from A. Draw and label the locus of S.
