- Construct a Δ ABC in which AB = 6 cm, ∠A = 30° and ∠B = 60°, Construct another ΔAB’C’ similar to ΔABC with base AB’ = 8 cm.
- Draw a line segment AB = 6 cm. Divide it externally in the ratio 3: 5
- Draw a line segment AB = 6 cm. Divide it externally in the ratio 5: 3. Justify the construction.
- Divide a line segment of length 7 cm into three parts in the proportion 2: 3: 4.
- Divide a line segment of length 9 cm internally in the ratio 4: 3. Also, give the justification.
