Only when it has 2 equal acute angles and 1 obtuse angle that it is an isosceles triangle
If it has 2 equal acute angles and 1 obtuse angle then it is an isosceles triangle.

yes
An obtuse triangle or an isosceles triangle if the 2 acute angles are equal in size
If it has 2 equal acute angles and 1 obtuse angle then it is an isosceles triangle.
It doesn't matter if a triangle is isosceles, scalene, obtuse, acute... There are always 3 angles in a triangle (which add up to 180).
An isosceles triangle can have an obtuse angle and two equal acute angles in which all 3 angles add up to 180 degrees.
isosceles
It is an obtuse triangle having 1 obtuse angle and 2 different acute angles Or it is an isosceles triangle having 1 obtuse angle and 2 equal acute angles
If the 2 acute angles are equal then it is an isosceles triangle otherwise it is a scalene triangle.
Only when it has 1 obtuse angle and 2 equal acute angles can it be an isosceles triangle.
