Best Answer

The sum of the measures of a linear (not lieir!) pair is exactly 180 degrees. Each obtuse angle is greater than 90 degrees so the sum of two must be greater than 180 degrees.

They make a pair of acute angles and a pair of obtuse angles. In rotational order, the angles are acute, obtuse, acute, obtuse.

If they have the same angles.

There can be 0 to 5 right angles, or 1 to 6 obtuse angles in a hexagon.

Not triangle

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".

The acute angles would be 35.

Yes, but only 2 of them whereas the other two angles are acute and obtuse.

Not sure exactly what you mean.Supplementary angles are such that they sum to 180oObtuse angles are greater than 90o and less than 180o→ the sum of two obtuse angles is greater than 90o + 90o, ie is greater than 180oSo two obtuse angles can never be supplementary.For two angles to be supplementary they must be either:both right angles (90o each); orone acute (less than 90o) and one obtuse (greater than 90o and less than 180o).

no all angles are acute.

No, a triangle can't have more than 1 obtuse angle because all the angles have to equal 180 degrees, and an obtuse angle is larger than 90 degrees. if it had more than 1 obtuse angle, the angles wouldn't equal 180 degrees and you wouldn't be able to make a third angle.
