1. 8 math exercise 4.4

Q1 ( i ) Steps of construction :
1. Draw a line segment AB = 6.5cm.
2. Construct an angle ∠ABY= 45° at point B.
3. Construct an angle ∠BAX= 30° at point A.
4. BY and AX intersect each other at point C. Thus △ABC is required triangle.

Q1 ( ii ) Steps of construction :
1. Draw a line segment AB = 5.4cm.
2. Construct an angle ∠BAY= 45° at point A.
3. Construct an angle ∠ABX= 90° at point B.
4. AY and BX intersect each other at point C. Thus △ABC is required triangle.

Q1 ( iii ) Steps of construction :
1. Draw a line segment AB = 4.8cm.
2. Construct an angle ∠BAY= 30° at point A.
3. Construct an angle ∠ABX= 120° at point B.
4. AY and BX intersect each other at point C. Thus △ABC is required triangle.

Q1 ( iv ) Steps of construction :
1. Draw a line segment AB = 3.6cm.
2. Construct an angle ∠BAY= 45° at point A.
3. Construct an angle ∠ABX= 60° at point B.
4. AY and BX intersect each other at point C. Thus △ABC is required triangle.

Q2 : Steps of construction :
1. Draw a line segment AB = 8cm.
2. Construct an angle ∠BAY= 45° at point A.
3. Construct an angle ∠ABX= 45° at point B.
4. AY and BX intersect each other at point C. Thus △ABC is required triangle.

Q3 ( i ) Steps of construction :
1. Draw a line segment QR = 5.3cm.
2. With the help of protractor, draw two angles of 120° and 30° at points Q and R.
Both the angles intersect each other at point P. Thus △PQR is required triangle.

Q3 ( ii ) Steps of construction :
1. Draw a line segment GH = 4.5cm.
2. With the help of protractor, draw two angles of 30° and 60° at points G and H.
Both the angles intersect each other at point K. Thus △GHK is required triangle.

Q4 ( i ) Steps of construction :
1. Draw a line segment AB = 3.5cm.
2. Construct an angle ∠ABX= 90° at point B.
3. From the point A draw an arc of radius 6.8cm to intersect BX at point C.
4. Join point A to C. Thus △ABC is required triangle.

Q4 ( ii ) Steps of construction :
1. Draw a line segment AB = 4.7cm.
2. Construct an angle ∠ABX= 90° at point B.
3. From the point A draw an arc of radius 8.8cm to intersect BX at point C.
4. Join point A to C. Thus △ABC is required triangle.

Q4 ( iii ) Steps of construction :
1. Draw a line segment AB = 5.4cm.
2. Construct an angle ∠ABX= 90° at point B.
3. From the point A draw an arc of radius 7.6cm to intersect BX at point C.
4. Join point A to C. Thus △ABC is required triangle.

Q4 ( iv ) Steps of construction :
1. Take a line segment BZ with suitable length.
2. Construct an angle of 90° at point B.
3. From the point B draw an arc of radius 5cm to intersect BX at point A.
4. From the point A draw an arc of radius 9cm to intersect BZ at point C.
4. Join point A to C. Thus △ABC is required triangle.
