That depends on what you want to 'do' to them.
It helps to remember these two simple facts. They will solve
most of the problems that involve a 30-60-90 triangle:
-- The side opposite the 30 is (1/2 of the hypotenuse).
-- The side opposite the 60 is (1/2 of the hypotenuse) times the sqrt(3) (or 31/2).
A 30, 60, 90 triangle is a right triangle. It's one of the most common triangles to use to learn about the Pythagorean theorem.

special triangles: 45-45-90 triangle and 30-60-90 triangle
No because 30-60-90 triangles are right angle triangles
isosceles are 45-45-90
A 30, 60, 90 triangle is a right triangle. It's one of the most common triangles to use to learn about the Pythagorean theorem.
A 30-60-90 right triangle
90
It is a triangle that has these 3 angles at its corners: 30, 60 and 90 degrees. This is one of the more common triangles as many designs are laid out at 30 degrees or 60 degrees.
No, they have the same angles but may vary in size.
In a right triangle where two other angles are 30 and 60 degrees, the side opposite to the 30 degree angle has a length that equals the half of the hypotenuse length.
Acute triangles have all of their angles less than 90 degrees. Right triangles have one of their angles equal to 90 degrees. Obtuse triangles have one of their angles greater than 90 degrees. Also, the 45-45-90 triangle and 30-60-90 triangle are useful when trying to get exact answers in trigonometry.
90-30 = 60
