Question 1.
Draw the angles 70° and 110° by using protractor,
(i) ∠AOB = 70°
∠AOB = 70°

1. Draw a ray OA−→−
2. At ‘O’ erect a ray OB such that ∠AOB = 70°

(ii) ∠AOB = 110°
∠AOB = 110°

1. Draw a ray OA−→−.
2. At ‘O’ erect a ray OB−→− such that ∠AOB = 110°

Question 2.
Construct the angles 60° and 120° by using ruler and compass.
(i) ∠AOB = 60°
∠AOB = 60°

1. Draw a ray OA−→−.
2. Draw an arc with any radius (convenient) taking ‘O’ as a centre and cutting OA−→− at X.
3. Draw an arc with the same radius – taking X as a centre and meeting the previous arc at Y.
4. Join OY and produce it to B.
5. ∠AOB is formed.
6. ∠AOB = 60°

1. Draw a ray DA−→−.
2. Draw an arc with any radius taking ‘D’ as centre intersecting DA−→− at X.
3. Now draw two successive arcs from X intersecting the previous arc at Y and Z.
4. Join D and Z and produce DZ to I.
5. Now the angle formed ∠ADI is equal to 120°.

Question 3.
Draw a line segment PQ = 4.5 cm and construct its perpendicular bisector by using ruler and compass.

∠PMY = ∠QMY = 90°
So, PQ ⊥ XY

1. Draw a line segment PQ of length 4.5 cm.
2. Draw two arcs with centre P and radius > 12PQ on both sides of PQ.
3. Repeat step 2 with centre ‘Q’ intersecting the previous arc at X and Y.
4. Join X and Y and produce it on either sides to form XY−→−.
5. XY is the perpendicular bisector of PQ.

Question 4.
Construct ∠DEF = 60° and its angular bisector by using ruler and compass.

∠DEF = 60°
∠DEK = ∠FEK = DEF2=602 = 30°

1. Construct ∠DEF = 60°
2. Draw an arc with a convenient radius taking E as centre intersecting ED at X and EF at Y.
3. Draw two arcs with same radius taking X and Y as centres intersect¬ing at Z.
4. Join E, Z and produce it to K.
5. ∠DEK = ∠KEF = 30°.

Question 5.
Construct an angle 90° without using a protractor.
∠SRI = 90°

1. Draw a ray 𝑅𝑆−→−.
2. Draw an arc of convenient radius taking R as a centre and intersecting 𝑅𝑆−→− at X.
3. With the same radius draw two successive arcs from X intersecting the previous arc at Y & Z.
4. Draw bisector to YZˆ intersecting at I.
5. Join R, I.
