Name the triangles that are classified by angles. (1 point)
right, scalene, isosceles
scalene, isosceles, equilateral
acute, right, obtuse
obtuse, isosceles, acute
I chose the answer "scalene, isosceles, equilateral" but the correct answer is "acute, right, obtuse". Why is that?

Math Ms. Sue please 
Ms. Sue,
Scalene, isosceles, and equilateral all refer to the number of equal (or unequal) sides. Acute, right, and obtuse refer to their angles.
