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
Yeah
no its not
Usually, but not necessarily.
Yes to both
Sometimes an isosceles triangle but never a scalene triangle with 3 interior acute angles.
Yes, an acute triangle can also be scalene.
A scalene triangle is a triangle that has three unequal sides.
Yes
No.
It is an acute angled scalene triangle.
In an acute triangle, all three angles are acute.
No triangle is a quadrilateral.
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
A scalene triangle can have 1 obtuse angle and 2 different acute angles or it can have 3 different acute angles providing that the 3 angles in both scalene triangles add up to 180 degrees.
