This chapter we're going to teach you how to construct figures, what mid-parallel, angle bisector and perpendicular bisector is and how to calculate altitude. Below are again some exercises to see how much you already know!

1. 

a. Draw two points D and E which are 6 cm apart.

b. Draw the circle with centre D and a radius of 4 cm.

c. Also draw the circle with centre E and a radius of 4 cm.

d. Label the points of intersection of the two circles F and G and draw the quadrilateral DFEG.

e. Why is quadrilateral DFEG a rhombus?

2. In the parallelogram KLMN, angle K = 68^o, KL = 6 cm and KN = 4 cm.

a. Draw parallelogram KLMN.

b. Which angle is the same size as angle K?
