none of them. The cube has parallel and perpendicular and os does the cuboid.
The following are some examples of a shape with two flat face and one curved surface: A sphere intersected by two planes. An ellipsoid intersected by two plane faces. A paraboloid intersected by two plane faces. A cone intersected by two plane faces. A cylinder. A hyperboloid intersected by two plane faces.
Some do, some don't. A regular polyhedron such as the tetrahedron has none whereas an irregular one like the parallelepiped can have several.
There are many possible answers: a frustrum of a cone, a sphere or torus intersected by a pair of parallel planes, a circular prism (cylinder) are some.
Some do.
none of them. The cube has parallel and perpendicular and os does the cuboid.
squares
Railroad tracks or the number 11 are parallel lines. A cross or a small t are perpendicular lines. Also the two ll's in the middle of parallel are parallel lines.
Some people describe a cone that way.
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. Some of these have no parallel edges whereas a right hexagonal prism has 4 pairs of parallel faces.
A polygon need not have ANY perpendicular or parallel lines. For example, consider an equilateral triangle. It can happen that two sides of a polygon, extended if necessary, meet at a point where they form a 90 degree angle. Those two lines are perpendicular. There may be pairs of lines such that, no matter how far you extend them in either direction, they will never meet. Such lines are parallel. A triangle cannot have parallel lines but it can have perpendicular lines. Any polygon of 4 or more sides can have sides that are perpendicular or parallel (or some of each).
Neither: because one line, by itself, can be neither parallel or perpendicular. These characteristics are relevant only in the context of another line (or lines). The given line is parallel to some lines and perpendicular to others.
A kite, if the topmost angle is right and none of the others are.
Parallel: E, F, H, I, M, N, O (in some fonts), U, Z. Perpendicular: E, F, G, H, L, T. Many more letters have perpendicular lines in serif fonts. Also, there are letters, such as D, in which the ends of the curved section are parallel to one another and are perpendicular to the vertical element.
Some examples for parallel lines- railroad tracks, steps, buildings, paper, windows, ect. Some examples for perpendicular lines- stop sign, bridge, street intersection, driveway into a street, ect.
Prism, which a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms.
A regular pentagon does not have parallel or perpendicular lines. Some other possibilities include, but are not limited to:a circlean ovalan equilateral triangle or any triangle that is not a right triangle.(A right angle's lines are perpendicular. Those are what make it a 90 degree angle.)
