simply judging from the great pyramids at Egypt versus any other man-made structure in history, i'd say that the triangular prism is the sturdiest
A rhombus normally has no right angles (at the vertices). If a rhombus has right angles (at the vertices), it is called a square. The diagonals of a rhombus meet at right angles.
Any polygon with at least 7 sides CAN have 5 right angles.
The faces are always rectangles on prisms, so if it's a triangular prism the bases are triangles; if it's a rectangular prism, the bases are rectangles; if it's a hexagonal prism, the bases are hexagons. Any polygon can form the base of a prism. Some people also consider cylinders to be circular prisms. In which case any closed plane shape can form the base of a prism.
None. A sphere does not have any angles.
The lateral sides are usually rectangles so each would comprise four right angles. However, the bases can be any pair of congruent triangles.
A triangular prism has two triangular faces, a rectangular prism does not have any.
If a triangular based pyramid has any right angles it has three. (Think of the corner of a cube). There are many triangular based pyramids that do not have any right angles.
It is a triangular prism and any triangular prism is a wedge.
It need not have any. A right triangular prism has 12 pairs but could have 14.
There are three altitudes to any triangle and you need to specify which one.
A two dimensional regular pentagon does not contain any right angles. A pentagonal prism, however, contains up to 10 right angles.
False, the prism can be of any length.
Multiply the length of the prism by the area of the triangular face. How you find the area of the triangular face will depend on what information you have about the triangle: 3 sides, 2 sides and the included angle, 1 side and 2 angles, base and vertical height or any of a number of other sets of data.
yes it does
The bases of a prism are general polygons and can have any angles in the range (0, 360) degrees excluding 180 deg, subject only to constraints imposed by the polygon. The lateral faces are all rectangles (in a right prism) and they meet the bases at right angles.
