Question

In triangle ABC, DE parallel BC , AD = 2 cm , DB = 3 cm DE ratio BC is equal to ​

Answer 1

Answer: The answer to the above given question is option b.

Step-by-step explanation:

Given that in triangle ABC ,

AD = 2 cm

DB = 3 cm and DE ║ BC

In the Δ ADE and Δ ABC

Angle A is common

∠ ADE ≈ ∠ ABC ( corresponding angles )

Here two angles of triangle are equal to another two angles of another triangle. This is called A A or AAA theorem.

Therefore by A. A similar condition

so AD ÷ AB = DE ÷ BC

2 ÷ 5 = DE ÷ BC

So the DE : BC is equal to 2 : 5
