Question

plz solve this question​

Answer 1

Answer:

angle B=angle D

Step-by-step explanation:

in ∆ABC&∆DEF

AB/DE=BC/FD

->AB/ED=AC/EF

TO BE SIMILAR ∆ABC&∆DEF WE MUST HAVE

Angle B=Angle D

Answer 2

Given:

$\sf\large : \to \dfrac{AB}{DE} = \dfrac{BC}{FD}$

Find:

$\sf\large : \to when \: \triangle ABC \: and \: \triangle DEF \: will \: be \: similar$

Solution:

If two sides of a triangle are proportional to the corresponding two sides in another triangle, and their included angles are equal, then the two triangles are similar by SAS rule.

If $\dfrac{AB}{DC} = \dfrac{BC}{FD}$, then for two triangles ABC and DEF to be similar, the included angle must be equal. In this case, the included angles are $\angle$B and $\angle$D

Hence, the answer will be $\angle$B = $\angle$D
