A prism is a polyhedron (a many sided 3D shape) with two identical and parallel faces called the bases. The vertices of the two bases are joined by straight lines forming a number of rectangular faces. For example, a pentagonal prism consists of 2 pentagonal faces and 5 rectangular faces, and has 15 edges and 10 vertices.

What is another name for a triangular based prism?

You can call it a "triangular prism" rather than "triangular based prism" ... saying a prism is "triangular" imply that the base is a triangle. There's no other name that I know of. A prism is just a 3d shape, so all you have to say is <type of shape> + prism to get the point across.

How are a cylinder and a triangular prism different?

Both are prisms. A prism is a 3D shape which has a uniform cross section, so anywhere along it's length where you take a slice you always see the same shape. To say which prism you mean we add the name of this cross section 'triangular prism', 'hexagonal prism' etc. We have a special name for a circular prism - a cylinder. Also, a rectangular prism is a cuboid.
