Answer:

2 ways

Step-by-step explanation:

The best way to do this is to fix the position of the stranger and then arrange the two identical twins

The number of ways of knowing where the stranger will seat is 1! ways = 1 way

The number of ways of arranging the two identical twins is 2! ways = 2*1 = 2 ways

The number of sitting arrangements = 1 * 2 = 2 ways

igor_vitrenko [27]

Answer:

SAS Postulate.

Step-by-step explanation:

Two triangles are congruent if anyone of the following postulates is true:

SAS - Two corresponding sides and the included angles are congruent to each other.

SSS - All the three corresponding sides are congruent.

ASA - Two corresponding angles and the included sides are congruent to each other.

AAS - Two corresponding consecutive angles and sides adjacent to either of the angles are congruent.

HL - If the corresponding hypotenuses and one corresponding legs are congruent to each other.

Here, in the figure, two corresponding sides and the included angle between them are congruent to each other.

So, the two triangles are congruent by SAS postulate.
