**Past year trend**

The number of questions are pretty less but more regular for an examination like JEE Mains but for JEE advanced it is like 1-2 questions occasionally.

**Topics**

You obviously need to know how to compute:

1. The distance between two points, point and a line.

2. Point deviding the line in the ratio of 1:k

3. Angle bisector of two line

4. Reflection in a line, foot of perpendicualr from a point is another important area.

5. Lastly the area of traingle.

Occasionally there is a question relating to finding the locus of a point which satisfies a criterion.

Some times questions from these chapter are linked with properties of triangles like properties of circumcentre, orthocentre, centroid.
