Write an informal proof to show triangles ABC and DEF are similar. Please don’t answer if you don’t know!!

Mila [183]

Answer:

ΔABC ~ ΔDEF

Step-by-step explanation:

If the given triangles ΔABC and ΔDEF are similar,

Their corresponding sides will be proportional.

$\frac{\text{AB}}{\text{DE}}=\frac{\text{BC}}{\text{EF}}=\frac{\text{AC}}{\text{DF}}$

By substituting the measures of the given sides,

$\frac{4}{2}=\frac{6}{3}=\frac{2}{1}$

2 = 2 = 2

Since, corresponding sides of both the triangles are proportional, both the triangles will be similar.
