Yes to both
Sometimes an isosceles triangle but never a scalene triangle with 3 interior acute angles.
equilateral triangle, acute triangle, some isosceles and scalene triangles
An acute scalene triangle has none. An acute isosceles triangle has one and an [acute] equilateral has three.
A scalene triangle=======================2nd Opinion:That's an acute triangle.It's quite possible for it not to be a scalene triangle,e.g. if it's isosceles or equilateral.
there is equilateral triangle, right triangle, isosceles triangle, obtuse triangle, acute triangle, scalene triangle and oblique 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).
It can be, if two of the sides and two of the angles are equal. Triangles can be classified by their sides: equilateral, isosceles, scalene or by their angles: acute, right, obtuse. Combinations are possible.
It is possible for an isosceles triangle to be an acute triangle because, in an acute triangle all the angles have to be less than 90o.
A right triangle may be isosceles or scalene (though not at the same time), but never acute, since an acute triangle is defined as having all interior angles less than 90°. A right triangle by definition has one 90° angle.
3 vertices in a triangle, whether it is equilateral, isosceles or scalene; acute angled, right or obtuse.
No because an isosceles triangle has 2 equal base angles and an apex angle whereas a scalene triangle has 3 interior acute angles of different sizes
It is possible.
