Collinear points

In Fig.18A,B,C are collinear point and /_DBA=/_EBA .(i) Name two linear pairs (ii) Name two pairs of supplementary angles.

Take three collinear point A,B and C on a page of your note book.Join AB,BC and CA is the figure a triangle? If not,why?

Points A,B and C are collinear.Point B is the mid-point of the line segment AC.Point D is not collinear with the other points.DA=DB and DB=BC=10. What is the length of DC?

Which of the following points are collinear ?
