Mark three non collinear points $A, B$ and $C$ in your notebook. Draw lines through them, taking two points at a time. How many lines can u draw? Name them.

Mark a point $O$. Mark three collinear points $A, B$ and $C$ away on $O$. Draw lines through the points $O,A,B,C$ taking at a time. How many lines can u draw? Name them. Which of these are concurrent lines?

Name the lines in the figure. Can you find any concurrent lines? Can you find any parallel lines?

$A, B, C$ and $D$ are collinear points such that $AB=4 \mathrm{cm}, BC=3.5 \mathrm{cm}$ and $AD=10 \mathrm{cm}$.  Find the measures of $AC, CD$ and $BD$.

A line has no endpoints, but a line segment has two endpoints.

A ray has two endpoints.

State 'True' or 'False'.

Four lines can be drawn through four non-collinear points lying in a plane.

State 'True' or 'False'.

When two line segments are parallel they cannot have a common point
