Draw a number line and represent the points $-5$ , and $9$ on the number line. What is the midpoint of $-5$ and $9$ on the number line?

Measure the sides of the adjacent triangle and verify:

$\mathrm{AB}+\mathrm{BC}>\mathrm{CA}$

In the given figure, name four line segments.
 

Find the following case by measurement:

$PR-PQ=?$ [the line segment]

`

Identify and name the line segments and rays in the following figure.

Study the diagram. The line $l$ is perpendicular to line $\mathrm{m}$

Is $\mathrm{C}\mathrm{E}=\mathrm{E}\mathrm{G}$?

Measure the sides of the adjacent triangle and verify:

$CA+AB>BC$

Name all the line segments in the following figure.

Compare the two line segment given below using a divider.

Count the number of line segments drawn in the following figure and name them.

Verify, whether $\mathrm{D}$ is the mid-point of $\overline{\mathrm{A}\mathrm{G}}$.
