Answer 3

Для данного вопроса, мне нужно перевести его на английский язык, чтобы я мог дать подробный ответ. Переведенный вопрос будет звучать так:

Question: Provide a detailed answer. Specify the numbers of the correct statements. Indicate one or more correct answer options: In triangle ABC, angle A is adjacent to side AC. An acute triangle is isosceles. In an isosceles triangle, the median is the bisector. If the three sides of one triangle are respectively equal to the three sides of another triangle, then such triangles are equal.

Теперь я могу дать подробный ответ на английском языке:

In triangle ABC, angle A is adjacent to side AC. This statement is true. In a triangle, an angle is said to be adjacent to a side if it shares a vertex with that side.

An acute triangle is isosceles. This statement is false. An isosceles triangle is a triangle that has two equal sides, whereas an acute triangle is a triangle that has all angles less than 90 degrees.

In an isosceles triangle, the median is the bisector. This statement is true. In an isosceles triangle, the median drawn from the vertex angle (the angle opposite the base) is also the bisector of the base.

If the three sides of one triangle are respectively equal to the three sides of another triangle, then such triangles are equal. This statement is true. This is known as the Side-Side-Side (SSS) congruence criterion, which states that if the corresponding sides of two triangles are equal in length, then the triangles are congruent.

Therefore, the correct statements are: 1. In triangle ABC, angle A is adjacent to side AC. 3. In an isosceles triangle, the median is the bisector. 4. If the three sides of one triangle are respectively equal to the three sides of another triangle, then such triangles are equal.
