It's an isosceles triangle. an isosceles triangle has two congruent sides that have the same measures and the third side can be whatever measure. Those 2 congruent sides are called "legs"
No, a triangle cannot be constructed with sides of 2 in., 3 in., and 6 in. For three line segments to be able to form any triangle you must be able to take any two sides, add their length and this sum be greater than the remaining side.
