no.. @mathstudent55

Ok. Let's start with that.

mathstudent55 · Answer

Equilateral triangle: all sides are congruent (equal length).
Isosceles triangle: at least two sides are congruent.
Scalene triangle: no two sides are congruent.
Right triangle: one angle is a right angle.

mathstudent55 · Answer

A right angle measures 90 degrees.
Is there a right angle in your triangle?

anonymous · Answer

It would be scalene triangle? @mathstudent55

mathstudent55 · Answer

Correct.

mathstudent55 · Answer

The lengths of the sides of a triangle are proportional to the measures of the opposite angles. Since all angles are different, all sides are different. That makes it scalene. Since there is no right angle it is not a right triangle either. The correct answer is C. scalene triangle.
