What kind of triangle has no equal sides or angles?

This is a SCALENE triangle.

There several types of triangle;

Equilateral ; The three sides are the same length and the three angles are ALL 60 degrees. All angles are ACUTE

Isosceles ; Two sides are the same length , and two angles have the same degree value. . May be ACUTE or OBTUSE.

Right angled ; The three sides may vary in length, but ONE angle is 90 degrees. Is ACUTE, and maybe ISOSCELES.

Scalene ; All three sides are of different length, and all three angles have different degree value. May be ACUTE or OBTUSE.

Fort ALL triangles , of whatever shape, the sum of the interior angles is ALWAYS 180 degrees.
