Question

What angle is included between the sides ab and bc of ∆abc?

Answer 1

Answer:

The angle included between the sides AB and BC of triangle ABC=angle B.

Answer 2

The angle which is included between the sides ab and bc of ∆abc, is ∠abc.

• A triangle is a three-sided polygon having three vertices and three edges. It is a fundamental geometric form. A triangle with vertices a, b, and c, is known as Δabc. In Euclidean geometry, any three non-collinear points form a unique triangle and, at the same time, a unique plane.
• In a triangle, there are three angles. Two sides of a triangle meet at a common point, known as the vertex, to produce these angles. Here the two sides of Δabc ab and bc meet and made an angel, namely ∠abc.
