Question

In a right angle triangle abc,ab=bc then tan(a-c)=???????

Answer 1

as ab =bc Tana =tanc applying the formula we get tan(a-c) = 0

Answer 2

Answer is 0

Given,

AB=BC,

AB=BC,That means it is a isosceles triangle.

AB=BC,That means it is a isosceles triangle.

AB=BC,That means it is a isosceles triangle. In a isosceles triangle 2 angles are equal {if one angle is 90 then sum of other two angles is 90 }

AB=BC,That means it is a isosceles triangle. In a isosceles triangle 2 angles are equal {if one angle is 90 then sum of other two angles is 90 }Then each angle is 45

so A=45

so A=45 C = 45

so A=45 C = 45 tan (a-c) = tan (45-45)

so A=45 C = 45 tan (a-c) = tan (45-45) = tan 0

so A=45 C = 45 tan (a-c) = tan (45-45) = tan 0 = 0.
