Ah, a triangular prism is a beautiful shape indeed. It has two right angles at each end of the prism where the triangle faces meet the rectangular faces. So, in total, a triangular prism has six right angles, creating a lovely balance of shapes and angles. Just remember, each angle is like a happy little friend adding to the harmony of the prism.
Zero!
A triangular block prism has four right angles on each of the three faces, so the total 'on all the faces' = 12.
14 if the triangular cross section has a right triangle, 12 otherwise.
A triangular prism has a total of nine angles. Each of the two triangular faces has three angles, totaling six angles. The three rectangular faces each have one right angle, adding three more angles. So, the total number of angles in a triangular prism is 6 + 3 = 9 angles.
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.
