If AB/DE=BC/DF in triangle ABC And triangle DEF both of these triangle

1.	If AB/DE=BC/DF in triangle ABC And triangle DEF both of these triangle will be similar if
Answer» $In \: \triangle ABC \:and \:\triangle DEF ,$ $\frac{AB}{DE} = \frac{BC}{DF} \: ---(1)(given)$ $\underline { \blue { Property \:of \: Similar \:Triangles :}}$ Two triangles are SAID to be similar if their , i) Corresponding angles are equal , II) Corresponding sides are proportional. / $Here, \frac{AB}{DE} = \frac{BC}{EF} \: --(<klux>2</klux>)$ / From (1) and (2) */ $If \: DE = EF \:then\: \triangle ABC \sim \triangle DEF$ Therefore., $\green { If \: DE = EF \implies \triangle ABC \sim \triangle DEF}$ •••♪
