Step-by-step solution

To ascertain whether BD is a side of triangle BCD, observe the basic geometric principles associated with triangles.

In Euclidean geometry, a triangle is named based on its vertices. For triangle BCD, it consists of three vertices: B, C, and D.

The sides of the triangle are the line segments directly joining these vertices. Thus, the sides of triangle BCD are:

  • Line segment BC, connecting vertices B and C.
  • Line segment CD, connecting vertices C and D.
  • Line segment BD, connecting vertices B and D.

Line segments such as BD connect two vertices within the triangle and thus qualify as one of its sides. This aligns with the standard definition of a triangle in Euclidean geometry, where any side is formed by connecting two of its vertices.

Therefore, indeed, BD is a side of triangle BCD.

The correct conclusion is true: BD is a side of triangle BCD.
