Three collinear points form a triangle.

Look at the following figure and name the points that are in the exterior of the angle:

Points $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ are collinear. Can you draw another line passing through $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}?$

Study the adjacent figure and fill in the table given below:

Look at the following figure and name the points that are in the points on arm of angle :

The points $\mathrm{P}, \mathrm{Q}, \mathrm{R}, \mathrm{S}$ are collinear. If points $\mathrm{S}, \mathrm{T}, \mathrm{A}, \mathrm{B}$ are collinear, then will the points $\mathrm{P}, \mathrm{Q}, \mathrm{R}, \mathrm{S}, \mathrm{T}, \mathrm{A}$, $\mathrm{B}$ always be collinear? Explain your answer with the help of a diagram.

In the figure given below, name four collinear points.

Look at the following figure and name the points that are in the interior of the angle :

Use the figure to name:

Five points

Study the given figure and answer the question.

Name the three points.
