An oxymoron. An equilateral triangle cannot be obtuse; an obtuse triangle cannot be equilateral.
No. It is not possible to make a equilateral triangle that is obtuse.
no they can be isosceles but not equilateral
No, an equilateral triangle can not be an obtuse triangle. All angles in an equilateral triangle are 60o. An obtuse triangle has 1 angle that is greater than 90o.
There cannot be an obtuse equilateral triangle. A rhombus is an equilateral quadrilateral with two obtuse angles (and two acute ones). Not sure if that counts as an obtuse equilateral. All regular polygons with more than four sides will be obtuse and equilateral. There are also other polygons that will meet these requirements. These will be squashed polygons in the same way that a rhombus is a squashed square.
No because an equilateral triangle is a regular polygon whereas an obtuse triangle is irregular
No if one angle is obtuse then they can't all be obtuse
no, obtuse must be greater than 90 (even when its 90.00000000001, its still considered obtuse), an equilateral triangle (if I translated your question correctly), can only have angles of 60. Basically, no.
No, none of them are.
