D, Obtuse means greater than 90 degrees, interior angles of a triangle add to 180 degrees.

Answer 2

What does equilateral mean?

Answer 3

All angles equal

Answer 4

(Any by extension all sides)

Answer 5

Right. This is to fluttermath, since he asked the question, but if all the angles are equal, then, what is each angle equal to in degrees? Then, what does obtuse mean?

Answer 6

Isosceles and right... yes. Equilateral and equilangular... they have to be. Scalene andand obtuse... yeah. But they can't be obtuse and equilateral b/c an angle in an equilateral triangle has to be 60. Obtuse is over 90
