Explanation:

Step1: Check triangle type

An acute triangle has all angles less than \(90^{\circ}\). Sasha's triangle has an angle of \(100^{\circ}\), which is obtuse.

Step2: Check isosceles property

An isosceles triangle has two equal sides. Sasha's side lengths \(6\) cm, \(9\) cm, \(12\) cm are all different.
