In an isosceles triangle, one angle is 70∘. The other two angles are of
i) 55∘ and 55∘
ii) 70∘ and 40∘
iii) Any measure
In the given option(s) which of the above statement(s) are true?
a) (i) only
b) (ii) only
c) (iii) only
d) (i) and (ii)
As we know, the sum of the interior angles of a triangle is 180∘
i) According to the question,
ii) According to the question,
iii) Not possible, because two angles must be equal in an isosceles triangle.
So (i) and (ii) can be possible.
