MAHARASHTRA Class 10: Areas of Similar Triangles Videos | Relation between the area of similar triangles and their corresponding sides

If two triangles are similar, then the ratio of their areas is equal to the ratio of 

If ∆ABC and ∆DEF are similar such that 2AB = DE and BC = 8 cm, then EF = 

If ∆ABC and ∆DEF are two triangles such that , find ∆ABC : ∆DEF.
