An obtuse triangle has 1 obtuse angle and 2 acute angles which add up to 180 degrees.
false
The base angles are always congruent.

False
true
Sometimes. "Scalene" simply means that the three sides have different lengths. This does not imply that the triangle has to have an obtuse angle.

It's true that an obtuse triangle is never right because obtuse triangles are bigger than right triangles, which are 90 degrees. Obtuse Triangles are always bigger than Right triangles(90 degrees) , so It is true.
Yes, its not possible to have a "right obtuse triangle"

An obtuse triangle must have two acute angles and these can be congruent.
The sum of the interior angles on an Obtuse Triangle is 1800 . This is true of ALL triangles.
No
No, it is not true that an obtuse triangle has two acute triangles. An obtuse triangle has one obtuse angle (greater than 90 degrees) and two acute angles (less than 90 degrees). However, the triangle itself is classified as obtuse, not as having two acute triangles within it.
