1. 8 math exercise 4.3

Q2 ( i ) Steps of construction :
1. Draw a line segment AB = 8.4cm.
2. Construct an angle ∠BAK = 60° at point A.
3. Take point C on AK such that AC = 5.5cm.
4. Join point C to point B. Thus △ABC is required triangle.

Q2 ( ii ) Steps of construction :
1. Draw a line segment AB = 7.5cm.
2. Construct an angle ∠BAK = 45° at point A.
3. Take point C on AK such that AC = 4.2cm.
4. Join point C to point B. Thus △ABC is required triangle.

Q2 ( iii ) Steps of construction :
1. Draw a line segment AB = 6.8cm.
2. Construct an angle ∠BAK = 30° at point A.
3. Take point C on AK such that AC = 4.6cm.
4. Join point C to point B. Thus △ABC is required triangle.

Q2 ( iv ) Steps of construction :
1. Draw a line segment AB = 5.4cm.
2. Construct an angle ∠BAK = 120° at point A.
3. Take point C on AK such that AC = 3.6cm.
4. Join point C to point B. Thus △ABC is required triangle.

Q3: Steps of construction :
1. Draw a line segment AB = 6.4cm.
2. Construct an angle ∠BAK = 30° at point A.
3. Take point C on AK such that AC = 6.4cm.
4. Join point C to point B. Thus △ABC is required triangle.

Q4 ( i ) Steps of construction :
1. Draw a line segment AB = 5.8cm.
2. With the help of protractor, draw an angle of 30° at point B.
3. Take point C on BK such that BC = 3.6cm.
4. Join point C to point A. Thus △ABC is required triangle.

Q4 ( ii ) Steps of construction :
1. Draw a line segment PQ = 4.8cm.
2. With the help of protractor, draw an angle of 120° at point Q.
3. Take point R on QK such that QR = 4.8cm.
4. Join point P to point R. Thus △PQR is required triangle.
