Yes, they exist.
Yes, an acute triangle can also be scalene.
In an acute triangle, all three angles are acute.
An acute scalene triangle has none. An acute isosceles triangle has one and an [acute] equilateral has three.
A scalene triangle or an equilateral triangle
It is an obtuse scalene triangle
Yes, an acute triangle can also be scalene.
A scalene triangle is a triangle that has three unequal sides.
Yes
No.
Yes, scalene triangles can sometimes be acute triangles. A scalene triangle is defined as a triangle with all sides of different lengths, while an acute triangle has all angles measuring less than 90 degrees. It is possible for a scalene triangle to have all its angles under 90 degrees, making it an acute scalene triangle.
It is an acute angled scalene triangle.
In an acute triangle, all three angles are acute.
No triangle is a quadrilateral.
NO
Yes, a triangle can be both scalene and acute. A scalene triangle has all sides of different lengths, while an acute triangle has all angles measuring less than 90 degrees. Thus, it is entirely possible for a triangle to meet both criteria simultaneously.
Yes to both
An acute scalene triangle has none. An acute isosceles triangle has one and an [acute] equilateral has three.
