A tetrahedron (a pyramid with a triangular base).
A 3D shape that has 4 corners and 4 faces is a tetrahedron. A tetrahedron consists of four triangular faces, with each vertex (corner) where three edges meet. It is one of the simplest three-dimensional shapes and is classified as a type of polyhedron.
a 4 sided 3d shape is called a triangular prism!!!!!!!!!!!!!!!
Yes
A square has no acute angles but it does have 4 right angle corners.
square
a square of course
A square and a rectangle both have 4 right angle corners.

A square or rectangular based pyramid is a 3D shape with 5 corners or points. It also has 4 triangular flat flaces, one square/retangular face and 8 straight edges.
Such a shape does not exits. See the attached link for all 3d shapes with 6 plane faces.
tetrahedron is a 4 faced 3d shape.
A rectangle.
There are 4 corners in a flat rectangle and 8 corners in a 3d rectangle(rectangular prism).Four.
a 4 sided 3d shape is called a triangular prism!!!!!!!!!!!!!!!
That 3D shape is called triangular pyramid.
Yes
A square has no acute angles but it does have 4 right angle corners.
