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."
3
A triangular pyramid. It has triangles on its 3 sides and a triangle on the bottom for a base.
Pyramid
the answer is pyramid
4 faces are triangles and 1 face is a square the square face is the base of the pyramid
3
A triangular pyramid. It has triangles on its 3 sides and a triangle on the bottom for a base.
Pyramid
TRIANGLES
a square pyramid has 4 triangles
a pyramid can use any triangles possible.
Triangular prism: 2 triangles, 3 rectangles Triangular pyramid: 4 triangles.
A triangle has only 2 dimensions, lenght and hight. a triangular pyramid has 3, length, width, and hight, and is made of 4 triangles
It makes a Triangular Pyramid.
A pyramid
A pyramid, with a triangular base.
In a pyramid, all the faces that go from the base to meet at the apex are triangles, one on each side of the base. For a square base pyramid, there are 4 sides to the base, so there are 4 triangles Be careful with a triangular based pyramid, there are 3 triangles from the base to the apex, but there is also the triangle of the base itself, so there are 4 triangles in a triangular based pyramid.
