yes, there can be an obtuse internal angle in a triangle, but keep in mind that the other two angles' sums plus the obtuse angle can only equal 180 degrees (meaning that the other non-obtuse angles will be very small acute angles)
Triangles do not have to have any obtuse angles but they can have one.
It has 3 interior angles one of which is an obtuse angle and the other two are acute angles and the 3 angles add up to 180 degrees.
An obtuse angle is greater than 90° (and less than 180° ) The other two angles therefore total less than 90° and so both must be acute angles.

Vertical angles are, by definition, equal. So if one is obtuse then so is the other.
yes
One angle must be an obtuse angle and the other two angles must be acute angles

No, a trapezoid does not have four obtuse angles. A trapezoid has one pair of parallel sides and the other pair of non-parallel sides. The angles of a trapezoid can be a combination of acute, obtuse, and right angles, but it cannot have four obtuse angles.
Trapezoids ALWAYS have at least one obtuse angle (if they have two right angles, then there will only be one obtuse angle), usually two (in any other circumstance, they will have two obtuse and two acute angles).
If triangle has one obtuse angle other two angles are acute. Since, sum of angles of triangle is 180.
A trapezium has one or two obtuse angles.
Triangles do not have to have any obtuse angles but they can have one.
Yes. A triangle can have only one obtuse angle. The other two angles will always be acute.
It has 3 interior angles one of which is an obtuse angle and the other two are acute angles and the 3 angles add up to 180 degrees.
You know that at least one of them must be acute. A quadrilteral can have three obtuse angles, but not four.
