Solution
The correct option is B similar
In a regular triangular pyramid, all of its faces are triangles.
(The base is an equilateral triangle and the lateral faces are triangles in any pyramid)
All the edges are equal in length.
Hence the triangles formed by all the faces are congruent triangles.
All congruent triangles are similar.
Therefore, the faces of a regular triangular pyramid are congruent and similar.
