Triangles do not have to have any obtuse angles but they can have one.
There is no triangle that has 2 equal obtuse angles because the 3 interior angles of any triangle must add up to 180 degrees and 2 obtuse angles would be over 180 degrees. It is possible for a triangle to have two equal acute angles in which case it would be an isosceles triangle.
yes an obtuse triangle has two acute angles
You can draw a triangle with two obtuse angles in a sphere
You will know that a triangle is obtuse if one of its angles is over 90°.
In normal geometry, it's not possible to make a triangle with two obtuse angles. It is possible to make a triangle with two obtuse angles in spherical geometry -- it's a kind of "spherical triangle". It is possible to make a triangle with two obtuse angles in some kinds of non-Euclidean geometry -- it's a kind of "non-Euclidean triangle".
No.
If by equilangular you mean all angles are the same, then no - the sum of the angles of a triangle must be 180o, so if all 3 are the same they must each be 60o and the triangle is called equilateral. However, an obtuse isosceles triangle is possible as the equal angles are the other two angles to the obtuse angle.
In spherical trigonometry this is possible
No an abtuse triangle can not have two obtuse angles
No triangle has 2 obtuse angles
No because two obtuse angles would be greater than 180 degrees and there are only 180 degrees in a triangle.
An obtuse triangle has 1 obtuse angle and 2 acute angles
No-An equilateral triangle has equal angles, an obtuse angle is greater than 90. So, an equilateral triangle with an obtuse angle would have the three angles add up to a MINIMUM of 270.0000000000001, and a triangle's angles must add up to 180°.

No not never can a triangle have 3 obtuse angles but it can have 3 acute angles
