Question

(ABC):A(DEF) are equilateral teingles A(ABC):A (DEF)=1:2 if AB=4 then find the DE​

Answer 1

Answer:

DE =4

Step-by-step explanation:

Given

angle ABC and angle DEF are equilateral triangles

DEF=1.2

AB=4 then we have to find DE

we know that

equilateral triangle means all angle & all sides are equal

therefore: triangle ABC and triangle DEF are congruent

therefore angle A is congruent to angle D

angle B is congruent to angle E

angle C is congruent to angle F

therefore seg AB is congruent to seg DE

so therefore AB =4

the

DE=4

because we know that equilateral means all angles and all sides are equal
