An obtuse triangle can have no right angles, and has two equal angles.
All triangles have 3 sides.
zero
Triangles can be classified based on their sides and angles. Based on sides, triangles can be equilateral (all sides are equal), isosceles (two sides are equal), or scalene (no sides are equal). Based on angles, triangles can be acute (all angles are less than 90 degrees), obtuse (one angle is greater than 90 degrees), or right (one angle is exactly 90 degrees).
By definition, all triangles have 3 sides.
None or two sides.
An obtuse triangle can have no right angles, and has two equal angles.
None
All triangles have 3 sides.

3 sides because every tiangle has 3 sides.
By definition, all triangles have 3 sides.
A scalene triangle has no equal sides.
Three equal sides in the form of an equilateral triangle and two equal sides in the form of an isosceles triangle
None!!!! EQUILATERAL TRiangle = 3 equal sides ISOSCELES Triangle = 2 equal; sides RIGHT ANGLED TRIANGLE = possible 2 equal sides. SCALENE Triangle = NO equal sides.
Every triangle has 3 sides but with a equilateral triangle all sides are equal
