Answer 1

In triangle ABC, the angle included by sides AB and AC is angle A, a fundamental aspect in understanding triangle geometry.

In a triangle ABC, the angle included by sides AB and AC is angle A. The term "included angle" refers to the angle formed between two sides of a triangle. In this context, angle A is the angle formed by sides AB and AC. It is the angle opposite side BC within the triangle.

Understanding the included angle is crucial in geometry, especially when working with different triangle theorems and postulates. The classification of triangles, such as whether they are acute, obtuse, or right-angled, often depends on the measures of these included angles.

In summary, in triangle ABC, the angle included by sides AB and AC is angle A, making it essential to consider when analyzing the properties and relationships within the triangle.

Answer 2

Each angle is formed from 2 sides intersected at its vertex

From the given figure we can see triangle ABC

Then the angle included by AB and AC is

The answer is B
