#### Question 1. Draw a line segment PQ =5.6 cm. Draw a perpendicular to it from a point A outside $\overline{\mathrm{PQ}}$ by using ruler and compass.

Given: A-Line segment PQ = 5.6 cm and a point A outside the line.
Required: To draw a 1 ar to PQ from point A.

Steps of construction :

(i) With A as centre and any suitable radius,
drawn an arc to cut the line PQ at points C and D.
(ii) With C and D as centres, drawn two arcs of equal radius ( > 1/2 CD)
cutting each other at B on the other side of PQ.
(iii) Join A and B to meet the line PQ at N,
then AN is the required perpendicular from the point A to the line PQ.

#### Question 2. Draw a line segment AB = 6.2 cm. Draw a perpendicular to it at a point M on AB by using ruler and compass.

Given: A line AB = 6.2 cm and a point P on it.
Required: To draw an ⊥ arc to AB at point P.

Step of Construction :

(i) With P as centre and any suitable radius,
draw an arc to cut the line AB at points C and D.
(ii) With C and D as centres,
draw two arcs of equal radius ( > 1/2 CD)  cutting each other at Q.
(iii) Join P and Q.
then QP is the required perpendicular to the line AB at the point P.

#### Question 3. Draw a line l and take a point P on it. Through P, draw a line segment PQ perpendicular to l. Now draw a perpendicular to PQ at Q (use ruler and compass).

Steps of construction :

(i) Let AB be the given line segment.
(ii) With A as centre and any suitable radius ( > 1/2 CD)
draw arcs on each side of AB.
(iii) With B as centre and same radius [as in step (i)],
draw arcs on each side of AB to cut the previous arcs at P and Q.
(iv) Draw a line passing through points P and Q,
then the lines PQ is the required perpendicular bisector of AB and line l.

#### Question 4. Draw a line segment AB of length 6.4 cm and construct its axis of symmetry (use ruler and compass).

Steps of construction :

(i) Draw a line segment AB  of length 6.4 cm.
(ii) With A as centre, using a compass, draw a circle.
The radius of this circle should be more than half of the length of AB.
(iii) With the same radius and with B as centre,
draw another circle using a compass.
Let it cut the previous circle at C and D.
(iv) Join CD. Then, CD is the axis of symmetry of AB .

#### Question 5. Draw the perpendicular bisector of XY whose length is 8.3 cm.

(i) Take any point P on the bisector drawn. Examine whether PX = PY.
(ii) If M is the mid-point of XY , what can you say about the lengths MX and MY?

Steps of construction :

(i) Draw a line segment XY  of length 8.3 cm.
(ii) With X as centre, using compass, draw a circle.
The radius of this circle should be more than half of the length of XY .
(iii) With the same radius and with Y as centre,
draw another circle using a compass.
Let it cut the previous circle at A and B.
(iv) Join AB.

(a) On examination, we find the PX = PY.
(b) We can say that the length of MX is Equal to the length of MY.

#### Question 6. Draw a line segment of length 8.8 cm. Using ruler and compass, divide it into four equal parts. Verify by actual measurement.

Steps of construction :

(i) Draw a line segment AB of length 8.8 cm.
(ii) With A as centre, using compass,
draw two arcs on either side of AB.
The radius of this arc should be more than half of the length of $\overline{\mathrm{AB}}$.
(iii) With the same radius and with B as ctntre,
draw another arc using compass.
Let it cut the previous arc at C and D.
(iv) Join CD.

(vi) With the same radius and with E as ceitre,
draw another circle using compass.
Let it cut the previous circle at F ana G.
(vii) Join FG . It cuts AE at H.
