Exercise 25(D)

1. Draw a line segment OA = 5 cm. Use set-square to construct angle AOB = 600, such that OB = 3 cm. Join A and B; then measure the length of AB.

Solution:

The length of AB = 4.4 cm (approximately)

2. Draw a line segment OP = 8 cm. Use set-square to construct ∠POQ = 900; such that OQ = 6 cm. Join P and Q; then measure the length of PQ.

Solution:

Measuring the length of PQ = 10 cm

3. Draw ∠ABC = 1200. Bisect the angle using ruler and compasses. Measure each angle so obtained and check whether or not the new angles obtained on bisecting ∠ABC are equal.

Solution:

Each angle measure = 600

Yes, the angles obtained on bisecting ∠ABC are equal

4. Draw ∠PQR = 750 by using set-squares. On PQ mark a point M such that MQ = 3 cm. On QR mark a point N such that QN = 4 cm. Join M and N. Measure the length of MN.

Solution:

The length of MN = 4.3 cm
