none because a triangle is not a 3D object
There is no such thing as a 3D triangle.
No.
No. A 3D triangle would be a triangular based pyramid.

A 3D triangle
To make a 3D paper star, you can start by folding a piece of paper in half diagonally to create a triangle. Then, fold the triangle in half again to form a smaller triangle. Cut three lines along the folded edges, leaving the center intact. Open up the paper and fold the cut edges inward to create the star shape. Finally, glue or tape the edges together to secure the star.

no.its a 3d shape of a triangle
To make a 3D star out of paper, you can start by folding a piece of paper in half diagonally to create a triangle. Then, fold the triangle in half again to form a smaller triangle. Next, fold the two outer corners of the triangle towards the center crease. Repeat this step on the other side. Finally, fold the top point of the triangle down and tuck it into the pocket created by the previous folds. This will create a 3D star shape.
A right angle triangle is a plane figure not a 3d one.
There is no such thing as a 3d triangle. A 3d shape which has only equilateral triangular faces can be a tetrahedron which has 4 faces or an icosahedron which has 20.
