concurrent lines. (begins with c) (5 marks)


4. The diagram below (fig 2) shows two lines AB and line PQ. When they meet like this they can be said to intersect
(word beginning with ‘ i ’)(5 marks)

(Fig 2)
5. This line has three points A,B and C. They are said to be collinear points.

(fig 1.)
6. A plane has no thickness, but extends infinitely. (begins with p)

The drawing above (fig 1.) is intended

7. When a line is extended, it can be said to have been
produced(word begins with p)(5 marks)





8. When two lines are parallel it means that they
