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 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 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 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
If the 2 acute angles are equal then it is an isosceles triangle otherwise it is a scalene triangle.
