What is a triangular pyramid?
In geometry, pyramid has many forms such as rectangular pyramid, trapezoidal pyramid, quadrilateral pyramid and even triangular pyramid. Triangular pyramid is a pyramid with triangular base and can be called as a tetrahedron if each of its faces has congruent equilateral triangles.
How many triangles does a pyramid have?
A pyramid has a variable number of triangular faces. The base of a triangle can be practically any regular shape, starting with a triangle. Technically a pyramid can have four or more triangles as faces.
It has 4 faces which are congruent triangles?
An equilateral triangular pyramid
What shape has 1 pentagon and 5 triangles face?
a pentagonal pyramid
Can a pyramid have 3 triangles?
The answer depends upon what is meant by "have 3 triangles?" The definition of a pyramid is "a solid having a polygonal base, and triangular sides that meet in a point." (Random House Webster's Unabridged Dictionary) Typical pyramids have a 4-sided quadrilateral base and 4 triangular sides, which means that it can be loosely said to also "have" 3 triangles as well as "have" 4 triangles. A pyramid with a triangular base would also have 3 triangular sides. If we include the shape of the base as a side of the pyramid, then no pyramid would have exactly 3 "sides."
