It has 12 right angles. 4 on each rectangular side. 3*4 = 12
14 if the triangular cross section has a right triangle, 12 otherwise.
There are twp perpendicular edges in a triangular prism. See if you draw a triangle you'll have two angles or edges that are the same length. That is if you draw a standard triangle.
There are normally three rectangular faces and so their angles are all right angles. But there are no restrictions on the angles of the triangular faces other than that they sum to 180 degrees.

A triangular prism can have right angles. If the prism has two triangular ends, then each of the three 'sides' meets each of the ends at right angles.

Zero!
A triangular block prism has four right angles on each of the three faces, so the total 'on all the faces' = 12.
A triangular prism reflects light at specific angles. Many are used in equipment such as binoculars and telescopes to reduce their physical size.

A triangular prism has 5 faces and 6 vertices. At each vertex it has three plane angles - making 18 two-dimensional angles.
14 if the triangular cross section has a right triangle, 12 otherwise.
A triangular prism has three rectangular faces which, between them, will have 4*3 = 12 right angles. It also has two triangular faces and these can have another 2 right angles. So the answer is 12 or 14, depending on whether the triangles are right angled or not.
