1. what does the word \included angle\ mean?
2. in △abc, ∠b is between sides ab and bc. which sides form the included angle?
3. if two sides and the included angle of one triangle are congruent to those of another, what postulate is used?

Explanation:

1. The included angle is the angle formed by two sides of a triangle.
2. In \(\triangle ABC\), sides \(AB\) and \(BC\) form the included angle \(\angle B\).
3. The Side - Angle - Side (SAS) postulate is used when two sides and the included angle of one triangle are congruent to those of another.

Answer:

1. The included angle is the angle formed by two sides of a triangle.
2. Sides \(AB\) and \(BC\) form the included angle \(\angle B\).
3. The Side - Angle - Side (SAS) postulate.
