The shape described is a triangular prism.
A rectangular-based pyramid.
The answer will depend on how the triangle is situated within the rectangle (how many of the triangle's vertices coincide with those of the rectangle), and what other information you have.
None since there is no such thing as a traingle! A triangle, on the other hand, has one face - the same as any two dimensional closed figure.
If a regular 2D shape - a square or rectangle - times the length by the width to get the area.If the shape is irregular than drawing squares inside the shape will aid in finding the total area. There are other ways worth studying.The area of a right-angle triangle is half the size of a rectangle or square. The triangle's base x side will give the area of the rectangle or square. Dividing by 2 will halve the rectangle or square, so giving the area of the right-angle triangle.
Triangles are polygons (two-dimensional) . Only polyhedrons have faces, verticles and edges. You could define as triangle as having either one or two faces (top/bottom), three vertices, and three edges.For pyramids and other polyhedrons, F + V - E = 2e.g.- a three-sided pyramid has 4 faces, 6 edges, and 4 vertices.- a four-sided pyramid has 5 faces, 8 edges, and 5 vertices

To each other no But individually a rectangle can be and a triangle can have congruent angles or sides
The area of qa triangle is always half of the area of a rectangle with the same dimensions
Rectangle has 4 sides, and triangle has 3 sides. So they are similar, they both have sides - one has more than the other :)

a hexagonal prism
It is a triangular prism
There is no such shape - unless there are other faces. If there is one rectangular face then you require at least four other faces - one on each edge of the rectangle - making a minimum of 5 faces.
