You can make a tube (or pipe) by using a rectangle and bending it around on itself. With two circles, you can close of each end of the tube to make a cylinder.

By its very nature of being a triangle, and a 2D shape, a triangle cannot have four plane faces. However, a tetrahedron is a polyhedron made up of four triangular faces.
There is no shape that is made up 3 sides that is not a triangle. Any shape that is made up of 3 sides is classified as a triangle no matter what shape or size it is.
because the airfoil shape makes tiny air molecules at the bottom slow down and the top speed up. The engine just pushes the plane.
A five sided shape is a pentagon
1 rectangle and 2 circle.

2D is a shape or an object that is flat and u can not pick it up, and it has 2 faces. 3D is a shape or an object that is a shape and you cant pick it up and hold it, and it can have as many faces.

An 8 sided octagon has 8 interior angles that add up to 1080 degrees
A liquid takes up the shape of a container without its volume changing.
calculate the length of each side then add them all up same with any 2d shape
To find the the area of a shape is to find the space that is enclosed within a 2D object. Do not mix it up with volume, which is the space enclosed within a 3D object.

The microscope doesn't have a cirtain shape but it is made up of a veriaty of shapes. the tube you look into is a cylinder shape the base is a square/rectangular shape and the platform is a square.
Yes. Corners is simply the more casual term. * * * * * Yes, but not all 2D shapes - a circle or an ellipse, for example, have corners. Nor does an irregular curved line that closes up on itself.
