Q. Take any two lines. Use the comparison by trace technique to compare the lengths.

Q. What is the disadvantage in comparing line segments by mere observation?

Q. Why is it better to use a divider than ruler, while measuring the length of a line segment?

Q. For any line segment, say $\overline{AB}$, take any point $C$ lying in between $A$ and $B$. Measure the lengths of $AB,BC$ and $AC$. Is $AB=AC+CB$ ?
[Note: If $A,B,C$ are any three points on a line such that $AC+CB=AB$, then we can be sure that $C$ lies between $A$ and $B$].

Q. If $A,B,C$ are three points on a line such that $AB=5cm,$ $BC=3cm$ and $AC=8cm,$ which one of them lies between the other two?

Q. Verify, Whether $D$ is the mid point of $\overline{AG}$.

Q. If $B$ is the mid point of $\overline{AC}$ and $C$ is the mid point of $\overline{BD}$, Where $A,B,C,D$ lie on a straight line, say Why $AB=CD?$

Q. Draw five triangles and measure their sides. Check in each case, if the sum of the lengths of any two sides is always greater than the third side.

Q. What is the angle name for half a revolution?

Q. What is the angle name for one-fourth revolution?

Q. Draw a situation of one-fourth, half, and three-fourth revolution on a clock.

Q. What fraction of a clockwise revolution does the hour hand of a clock turn through, when it goes from $3$ to $9$.

Q. What fraction of a clockwise revolution does the hour hand of a clock turn through, when it goes from $4$ to $7.$

Q. What fraction of a clockwise revolution does the hour hand of a clock turn through, when it goes from $7$ to $10$.

Q. What fraction of a clockwise revolution does the hour hand of a clock turn through, when it goes from $12$ to $9$.

Q. What fraction of a clockwise revolution does the hour hand of a clock turn through, when it goes from $1$ to $10$.

Q. What fraction of a clockwise revolution does the hour hand of a clock turn through, when it goes from $6$ to $3?$

Q. Where will the hand of a clock stop if it starts at $12$ and makes $1/2$ of a revolution, clockwise?

Q. Where will the hand of a clock stop if it starts at $2$ and makes $\frac{1}{2}$ of a revolution, clockwise?

Q. Where will the hand of a clock stop if it starts at $5$ and makes $\frac{1}{4}$ of a revolution, clockwise?
