Remember the following kinds of triangles:

By angle:

- Acute triangle: has three angles less than 90º.

-Right triangle: Has one angle that measures exactly 90º.

-Obtuse triangle: Has one angle greater than 90º.

By sides:

- Equilateral triangle: Has three equal sides.

- Isosceles triangle: has two equal side and one side different from the others.

- Scalene triangle: has no equal sides.

Since larger sides are opposite to larger angles, then, a triangle with angle measures of 66º, 82º and 32º cannot have equal sides (they should be opposite to equal angles).

Therefore, a triangle with angle measurements of 66º, 82º and 32º is a scalene triangle.
