Question

For being an obtuse angled triangle, how many angles of triangle should be greater than 90°?

Answer 1

Answer:

An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. Since a triangle's angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle.

Answer 2

Answer:

1 angle should be greater than 90
