**Problem Set 25 : **

**Question no – (1) **

**Solution : **

**Figure – (i)**

We know the steps to measure the angle,

- Place the origin of protractor over vertex
- One arm of angle is in zero point of protractor
- Align the base line of protractor with second arm of angle
- See which mark falls on that arm
- The no at that point is angle between this two arms

**Problem Set 26 : **

**Question no – (1) **

**Solution : **

**(1) The steps to draw the angle 60°**

- Draw a straight line
- Give the name of that line PQ it is a one arm of angle
- Place the origin of protractor over any point P or Q it is the vertex of angle
- PQ line is in zero point of protractor
- Find the 60 on protractor and mark in paper at that point
- Using the ruler join the mark with vertex
- Give the name of that line is QR it means that Q is vertex
- In this way we draw the PQR of 60°

**(2) The steps to measure the angle 90°**

- Find the 90 on protractor and mark in paper at that point
- Using the ruler join the mark with vertex
- Give the name of that line is QR it means that Q is vertex
- In this way we draw the PQR of 90°

**(3) The steps to measure the angle 150°**

- Draw a straight line
- Give the name of that line PQ it is a one arm of angle
- Place the origin of protractor over any point P or Q it is the vertex of angle
- PQ line is in zero point of protractor
- Find the 150 on protractor and mark in paper at that point
- Using the ruler join the mark with vertex
- Give the name of that line is QR it means that Q is vertex
- In this way we draw the PQR of 150°

**(4) The steps to measure the angle 30°**

- Draw a straight line
- Give the name of that line PQ it is a one arm of angle
- Place the origin of protractor over any point P or Q it is the vertex of angle
- PQ line is in zero point of protractor
- Find the 30 on protractor and mark in paper at that point
- Using the ruler join the mark with vertex
- Give the name of that line is QR it means that Q is vertex
- In this way we draw the PQR of 30°

**(5) The steps to measure the angle 165°**

- Draw a straight line
- Give the name of that line PQ it is a one arm of angle

**Problem Set 27 : **

**Question no – (1) **

**Solution : **

**The example of parallel line see in environment are – **

**(1)** We know that parallel lines do not intersect the railway track lines are not intersect they are parallel to each other

**(2)** We know that parallel lines do not intersect the zebra crossing on the roads are not intersect they are parallel to each other.

**Question no – (2) **

**Solution : **

**The example of perpendicular line see in environment are**

**(1)** We know that perpendicular lines are intersect each other the addition symbol lines are intersect.

**(2)** We know that perpendicular lines are intersect each other the two arms of the scissors are intersect each other.

**Question no – (3) **

**Solution : **

In the above picture two lines do not intersect each other

So, they are parallel to each other.

In the above picture two lines are intersect each other

Hence, they are perpendicular to each other.

In the above picture two lines do not intersect each other

So, they are parallel to each other

In the above picture two lines do not intersect each other

Thus, they are parallel to each other

In the above picture two lines intersect each other

Therefore, they are perpendicular to each other.
