Question

if one angle of a triangle is greater than the sum of other two show that the triangle is obtuse angled​

Answer 1

Answer:

In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°. Here, the triangle ABC is an obtuse triangle, as ∠A measures more than 90 degrees. ... Hence, if one angle of the triangle is obtuse, then the other two angles with always be acute.
