Question

if triangle ABC congruent to triangle EDF and triangle ABC is not similar to triangle d e f then which of the following is not true​

Answer 1

Use SSS Similarity Rule

Explanation:

As per the SSS Similarity rule of similar triangles, sides of both the triangles are proportional to each other, which makes their angles also equal.

∆ABC ∼ ∆EDF

$\frac{ab}{ed} =\frac{bc}{df} =\frac{ac}{ef}$

(By similarity property)

Taking first two terms, we get

$\frac{ab}{ed}=\frac{bc}{df}$

⇒ AB.DF = ED.BC

So, option (d) is true

Taking last two terms, we get

$\frac{bc}{df}=\frac{ac}{ef}$

⇒ AB.EF = ED

Hence, option (b) is true..AC
