Question

Two triangles are similar , if their corresponding angles of two triangles areequal and corresponding sides are in the same ratio. Is it true?

• A. Yes
• B. Not of same size
• C. Not sure
• D. Cannot be possible

Answer 1

Answer: (A)

Yes

In $\Delta ABC$ and $\Delta DEF$

$\angle A=\angle D,\angle B=\angle E,\angle C=\angle F$

And $\frac{DE}{AB}=\frac{EF}{BC}=\frac{FD}{CA}$, then 2 triangles are similar.

Therefore, A is the correct answer.
