What 3D shapes have triangular faces?
In geometry, a deltahedron (plural deltahedra) is a polyhedron whose faces are all equilateral triangles. The name is taken from the Greek upper case delta (Δ), which has the shape of an equilateral triangle.
What is the difference and similarities between a prism and a pyramid?
a prism is constructed from two parallel and congruent regular polygons. with vertices joined by edges of length equal to that of the polygons a pyramid has a square base and has 4 triangle joining at a vertex above the centre of the square base. the triangles are isosceles triangles (and can even be equilateral)
Does a triangular prism have one square face?
yes it can, if the length and width of the non-triangular face(s) are the same. eg a triangular prism with triangles of side lengths 3 cm 4 cm & 5 cm and length between the end triangles of 5 cm will have one square face. If the ends are isosceles or equilateral triangles with the side of equal length the same as the length of the prism it will have 2 or 3 square faces.
What is a shape with 2 triangles at either end joined with 3 rectangles called?
triangular prism
