TRY THESE :

Question 1.

In step 2 above, what would happen if we take the length of radius to

be smaller than half the length of \(\overline{\mathrm{AB}}\) ?

Solution:

If we take the radius to be smaller than half of the length of \(\overline{\mathrm{AB}}\), the arcs will not intersect each other at two points C and D.

Question 1.

How will you construct a 15° angle ?

Solution:

Construct of angle an 30° as shown earlier.

Now bisect this angle. We get ∠AOD = 15° [Fig.],

Question 1.

How will you. construct a 150° angle ?

Solution:

Construct an angle of 120° as shown earlier.

Now ∠POQ = Straight angle – 180°

∠QOC = 120°

∠POC = 180° – 120° = 60°

Bisect ∠POC to get ∠COD = 30°

Thus, ∠QOD = ∠QOC + ∠COD = 120° + 30° = 150° which is the required angle.

Question.

How will you construct a 45° angle ?

Solution:

Construct ∠QOC = 90° as shown earlier. Raw \(\overrightarrow{\mathrm{OD}}\) as the bisector of ∠QOC.

Thus, ∠QOD = 45° is the required angle.
